The irony of this didn’t escape me: While I’d been drawn to freeze-dried food as a convenient way of preparing for a cataclysm that may never come, there I was, toiling away for hours in the kitchen to prepare a dish I’d be eating that night and the next day. It was the most fortifying meal I’d eaten all week, and a minor achievement: Thanks to the premeasured portions and easy-to-follow instructions, I’d learned how to make a chicken pot pie from scratch.
All good questions and points. Shipping containers are definitely not a good option. They are typically made of 16 and 14 gauge corrugated steel (.065 and.075 inches respectively) and the amount of retrofitted fortification that would be required to withstand the weight/pressure of several feet of earth is considerable. The container would have to be buried fairly deep(as most steel shelters are) since it offers little protection, in and of itself, against radiation, heat or even small arms fire due to it’s light construction. Then of course there would be waterproofing required(although they are made to be exposed to weather,they… Read more »
Some products are no different than a normal box of mac and cheese: you boil water in a pot, mix the packaged product into the pot, turn the heat to a simmer, cook, and serve. Others are as simple as pouring boiling water in the pouch and waiting a few minutes. In some cases, the water doesn’t even need to be hot (although flavor and texture is better if it is).
The fortress does not only showcase its dreamy amenities, but it also guarantees safety against asteroids, chemical attacks, nuclear explosion, zombie outbreak, and more. Its three-foot upgraded concrete walls can withstand a 20-kiloton nuclear blast. It is also equipped with decontamination showers, solar power backup, private water systems, secure air intake and HVAC.
I keep several five gallon gas cans filled and ready for use. I don’t put any gas stabilizers in them, but I have stabilizers on hand. At the end of each quarter, I fill the cars with the gas from these cans, and go and get fresh. If the SHTF, and it looks like more time would be needed for the gas to keep, then and only then would I add the stabilizers to the gas.
You should be doing your homework and putting in practice ahead of the fateful day, not counting on whipping out your manual in the middle of a crisis, but knowing how to best deal with any given situation is too good to pass up. In lieu of first-hand experience, a good set of instructions can help carry the day. I really like the Pocket Ref guides for general knowledge and skills, as they are tiny and positively packed with useful info.

Zionism is one of the causes of current West Asian, and American political, problems.Your ‘representatives’ have sold out Americans (and other populations) for political contributions (and actual bribes). The annual many billions given to the Zionists have gotten used and recycled to skew behaviors and matters. Not least among candidates and your putative representatives.

Thanks, Viet Nam Vet. People keep calling us a democracy but that is not our form of government. Our founding fathers were reluctant to have a true democracy because they correctly feared mob rule. It doesn’t bother me that government moves slowly. That keeps it from swaying to and fro in shallow breezes. Congress was supposed to be a deliberative body. The Supreme Court was supposed to be an even more deliberative body. Rapid response is only acceptable in the troops coming to your rescue, not in governments.


When country leaders fail to stop a nuclear war or a mad scientist spreads an airborne virus that can turn every living being into a flesh-eating zombie, a perfectly shielded underground place filled with complete amenities is exactly where everyone would want to be trapped into. Surprisingly, such dreamy, luxurious, and sci-fi-like underground bunkers exist in different parts of the world.
I very much agree the article was amazingly detailed but i am neutral about the permits…on one hand you can get them and the county will have on paper where your bunker is which by the way the general public can look at or take the risk of no permits and guarantee that no one other then yourself and whoever you choose knows the location of you bunker….personally i would take the risk….
While not all household conditions are perfect, be aware of the six enemies of food storage and do your best to mitigate their effect on your precious food supply.  This means you should avoid storing food in garages that are 90 degrees in summer and 30 degrees in winter.  I am repeating what I said before but it is important: empty your cupboards and closets of excess stuff and stow these items in the basement, attic, or garage.  This will make room for you to store your food inside your main living area where the ambient room temperature is stable.
Based on factors like the proliferation of nuclear weapons, global political tensions, and unchecked climate change, scientists said the symbolic clock was poised at three minutes to “midnight,” a.k.a. doomsday, in 2015 and 2016. That’s considered a very high-risk state of affairs—much worse than 2010 (six minutes to midnight) or the end of the Cold War circa 1991 (17 minutes to midnight).
If you managed to get lard and salt, you need to get some cornmeal as well because it is better to keep on hand than flour. Corneal requires fewer ingredients to make bread, and it has a longer shelf life. A few 5lb bags of cornmeal should last until the emergency situation ends. You can make a skillet cake using just lard, salt, and cornmeal and I had the pleasure of eating such food on various occasions during my camping trips.
There wasn’t much weather tracking prior to the late 19th century. Certainly, some individuals kept track of the weather as best they could locally, but it wasn’t organized into a regional or national scale perhaps until the mid 20th century. I am reading about the great desolation of the 1930s in the Eastern Colorado, Western Kansas, Oklahoma panhandle, North Texas area and even in the 1930s weather tracking was at best primitive. Dust storms came as big a surprise to the weather bureaus of the region as it did to the farmer on the ground.
Not to mention the “year without a summer” that happened after the eruption of Mt. Tambora in the Dutch East Indies in 1815. The resulting ash and smoke plume blocked the sun enough to lower the average temperatures only by a few degrees. It was enough to trigger famines in North America and Europe for several years until temperatures gradually normalized. If the Yellowstone caldera erupts the smoke and ash would block the sun much as would a nuclear winter and would trigger even worse famines and suffering from people trying to cope with minimum if any infrastructure for heat, water, medical, etc. just for the simple reason that we’ve got way more people now and more of us live in urban areas.
Interest in the movement picked up during the Clinton administration due in part to the debate surrounding the Federal Assault Weapons Ban and the ban's subsequent passage in 1994. The interest peaked again in 1999 triggered by fears of the Y2K computer bug. Before extensive efforts were made to rewrite computer programming code to mitigate the effects, some writers such as Gary North, Ed Yourdon, James Howard Kunstler,[18] and investments' advisor Ed Yardeni anticipated widespread power outages, food and gasoline shortages, and other emergencies. North and others raised the alarm because they thought Y2K code fixes were not being made quickly enough. While a range of authors responded to this wave of concern, two of the most survival-focused texts to emerge were Boston on Y2K (1998) by Kenneth W. Royce, and Mike Oehler's The Hippy Survival Guide to Y2K. Oehler is an underground living advocate, who also authored The $50 and Up Underground House Book,[19] which has long been popular in survivalist circles.
Additionally, some people may want to prioritize skills over supplies, the idea being if you have the skills you can make or find everything else. I will not derail the discussion by delving too far into that, but the fact is having what you need on hand will always save you labor and time. A truly skilled individual can sustain themselves with rudimentary or even no tools in very austere conditions, and there is no substitute for that kind of mastery, but no “lone survivor” who is honest would choose to go without provision or tools when the chips are down and they had a choice.
This group is concerned with the spread of fatal diseases, biological agents, and nerve gases, including swine flu, E. coli 0157, botulism, dengue fever, Creutzfeldt–Jakob disease, SARS, rabies, Hantavirus, anthrax, plague, cholera, HIV, ebola, Marburg virus, Lassa virus, sarin, and VX.[36] In response, they might own NBC (nuclear, biological and chemical) full-face respirators, polyethylene coveralls, PVC boots, nitrile gloves, plastic sheeting and duct tape.
Batteries- Your primary battery-gobblers will be the above flashlights and battery-powered lanterns. Make sure you have plenty of each type you need for all your lights. You can make your life easy by limiting your battery consumption on lights to two types of cell; perhaps one kind for flashlights and headlamps, and one for lanterns. Or you might have one type for low-output utility lights, and another, perhaps CR123 cells for your high-output work and weapon lights.
Our testers unanimously voted MH the best tasting, even going as far as to buy some to use in everyday life. Nutritionists we spoke with thought MH had the best overall nutritional value, too, with tons of meat-based proteins and fiber. It’s also the most convenient to cook. No external dishes needed, just pour some (ideally boiling) water into the pouch, let it cook, eat, then trash.
We placed these on heavy-duty shelves, $39–49 at Lowe’s. Plastic totes are great for storing sauce bottles, small cans, etc. just make sure to rotate your stock. If you find someone who is like-minded, you can share things like 50 pound bags of pinto beans, rice, etc. We got corn and wheat from the feed store. No need for expensive freeze-dried MREs. Two IBC totes and a Berkey water filter and you can survive hurricanes, natural disasters and snowbird season here in Florida. Welcome to the world of just common sense.
If a crisis persists for a long enough period of time, it is very difficult to have an extended comprehensive food stock pile. Having the ability to grow vegetables is a great supplement to your stored foods. Be sure to have varieties that do well in your area, in your soil, and that you know how to grow. Have seeds for medicinal herbs and flavorful spices as well.
Atlas Survival Shelters takes pride in finishing out your shelter to the means you are used to living in your home. Any wood materials used in an Atlas Shelter is either a hard wood or kiln-dried to ensure longevity. Making a shelter feel like you’re in the county jail takes away the normality you would need to survive long term underground in a survival shelter.
As someone who reads a lot on the internet, you have likely come across many authorities with “expert” advice on one topic or another.  This is where the gray matter between your ears becomes the most important tool in your box of prepper skills.  Think it through before you unilaterally apply someone’s expertise to your own situation.  Let me repeat: this includes advice and suggestions from this website!
The MPS totes let in a little water when we submerged them. And the tote lid bent a little under the weight testing, but did not collapse or hurt the food. As expected, the cardboard boxes containing Mountain House foods got soggy immediately. But the packets of food themselves are waterproof. The boxes stacked well but didn’t offer nearly the same protection as the buckets.
Survivalists maintain their group identity by using specialized terminology not generally understood outside their circles. They often use military acronyms such as OPSEC and SOP, as well as terminology common among adherents to gun culture or the peak oil scenario. They also use terms that are unique to their own survivalist groups; common acronyms include:

Water is pumped from two water wells, reaching thousands of feet deep into an artesian aquifer, then stored within the massive underground, reinforced concrete water tanks, with a water distribution system being deployed to each bunker. Each bunker is buried and protected under thick berms of earth, with extensive grading for drainage, across the gently sloping grasslands.
Check out the full review of the best emergency water storage containers and tips on how to store water. We recommend that you have the two weeks of water ready, sitting in their containers. Don’t depend on finding and filtering water or filling your bathtub for this two week period. It’s very likely you’ll have access to portable water filters and other methods because of your bug out bags, but think of those as a bonus backup.
One of the biggest issues with GMO food is the allergy cross-over. Because genes from nuts, fish, soy and other highly allergenic plants/animals are used in the to give the need seed the desired characteristics, they can trigger serious allergic reactions in people who had no way of knowing the food was dangerous or even which food it was that caused it! If that wasn't bad enough already, it will certainly only be worse in a grid-down situation where medical care is limited at best.
Your second gun should be a good hunting rifle. Bolt or semiauto is fine, and the ideal caliber is .308. Ammo is cheap and widely available because you can use 7.62mm NATO as well. It also has enough punch to take down just about any game. A handgun is a lower priority, but handy to have. Go for a high-capacity 9mm semi, if you’re buying one. Again the ammo is NATO standard and easy to find.
Few people get beyond storing the four basic items, but it is extremely important that you do so. Never put all your eggs in one basket. Store dehydrated and/or freeze-dried foods as well as home canned and store-bought canned goods. Make sure you add cooking oil, shortening, baking powder, soda, yeast and powdered eggs. You can’t cook even the most basic recipes without these items. Because of limited space I won’t list all the items that should be included in a well-balanced storage program. They are all included in the The New Cookin’ With Home Storage cookbook, as well as information on how much to store, and where to purchase it.

I’m a grandfather now and I’m a positive person, but being a prepper can be tough. It’s difficult to get others on board, for most it’s a no-go subject. A lot of my friends think I’m barking mad. It’s taken me three years to convince my daughter and her family to take more of an interest and, before she eventually became a full-blown enthusiast, my partner used to humour me politely.
Monitor what your family eats for a week and use that as a guideline for getting started.  The advantage of doing this is you will learn what your family likes so that you can shop accordingly.  You would be surprised at how many people can’t remember what they ate yesterday let alone a week ago.  Try to write everything down so that you don’t have to rely upon your memory.
Purchasing survival gear is a necessary part of the prepping process but it should not be done to the exclusion of food, water, and medical supplies.  The exception to this rule is water purification and fire-making tools both of which can be acquired for very little cost. For example, consider pool shock for water treatment plus a magnesium fire tool and dryer lint for fire-making.
Nygaard is a busy woman: In addition to working a full-time job, raising chickens, and growing sweet corn, potatoes, and peppers, she runs a blog called Living Life in Rural Iowa, where she shares bits of wisdom that she’s learned on her prepping journey. Looking back, Nygaard says becoming a prepper encouraged her to develop new skills, including the sorts of home repairs and outdoor work she once counted on her husband to tackle. “Before you get divorced, you’re like, ‘Oh, that’s outside. My husband can take care of that.’ And then when you become a single parent, you’re like, ‘Wow, I have to do outdoors and indoors — why did I think he should take care of all that?’ You have that sense that you can do just about anything you set your mind to.”
“Everybody thinks about prepping as this big doomsday thing, like when the zombie apocalypse happens,” Luther says. “But really it’s a lot more likely that someone’s going to lose their job or that you’re going to have a major expense you weren’t expecting, like your car breaks down or a medical expense. So if you think of prepping as something to get you through those situations, it’s really almost like an insurance policy.”

To your closing, I’d like to add something that Solomon said in the book of Proverbs: “The prudent man sees danger and takes refuge, but the simple keep going and suffer for it.” So, we all should work, as Claude said, to keep making our personal situations stronger, and safer. God gave us incredible minds. Lets put them to good use. I like to do something every day; no matter how small it may be. Because, when you add up the little things, it turns into a great accomplishment.


Portable or Camp Stove and Fuel- A small, efficient stove for cooking and boiling water is invaluable and generally offers more convenience than doing either over an open fire unless you have a fireplace in home or a fire pit outside. Fuel types vary, but you may choose to rely on one that has small, self contained fuel cans or cylinders, or a pop-up model that is multi-fuel, relying on gas, alcohol, wood or charcoal.
You may actually be right, Illini Warrior. There’s something very strange going on with people. They seem to becoming more violent and destructive and I really don’t know what the cause is. Just this morning on the news I heard that another package exploded. I think it was in a UPS depot somewhere in the States. Apparently two people were killed and a number injured. I don’t know what people are thinking when they commit these kinds of atrocities. And we’re still supposed to be living in the “good times”. What’s going to happen when you deprive people of their creature comforts and have them starving at the same time. I shudder at the possibilities. I hope to god you’re wrong about 2018.
If you spend enough time on the survivalist internet, you’ll stumble upon a number of woman-run blogs specializing in a softer side of prepping, one that combines aspects of survivalism, healthy eating, and home economics. They have names like Survival Mom, Apartment Prepper, and Organic Prepper and can boast Facebook and Pinterest followings in the tens and hundreds of thousands. Together with a number of online forums and private Facebook groups, they form the basis of a loose-knit community with a shared interest in a constellation of traditional and contemporary domestic practices, including long-term and short-term food storage, growing and preserving food, frugal grocery shopping, family first aid, and basic self-defense. It’s a community found primarily online, but it also includes the occasional in-person trade expo or foraging class. For Jennifer and other mothers who partake in this feminine strain of survivalism, being prepared is more than a means of shoring up for some unseen future disaster. It’s a form of self-empowerment in the present.
Not so sure I agree with some of this list. Sure, you need to clean water, shelf-stable foods and alternative ways to cook it, but not so sure I would recommend beginning preppers bother with a rifle or seeds quite yet. I would suggest they worry about items like a comprehensive first aid and hygiene/sanitation concerns first. You need to be able to get through a disaster before you should worry about a long term survival scenario.
Thanks for the tips! I was actually thinking of doing a post on this but tweaking it to fit ranches. We had a major freeze this year that left us without power for over a week, and the freeze burnt our pump so we couldn't water. We also had several major wildfires that left us without cell service b/c a tower was disabled. I was totally unprepared. I thought we were going to lose everything in our freezer, I couldn't wash clothes or dishers (not a great experience if you have a house full of kids) and no way to communicate with anyone. And that is when a friend recommended your site. It's been so helpful! I think in addition to your list, one could also use a HAM radio or emergency radio, a solar pump if you have a well, and alternative light sources.
Great read, but #14 in my opinion is not good. Why is it always the prepper in the family that has to compromise? Prepping is not a number one priority, it is the only priority. There is nothing but prepping. It is not a way of life, it is life itself. What good will prepping do anyone if they are away on vacation when the lights go out or a nuclear blast occurs? What good is anything connected with survival if it is not with you 24/7/365.25? One window of opportunity is all an intentional or happenstance enemy needs to cull a prepper. Life is life and death is death and their is no inbetween. A little bit of further advice on bugging out, if you will allow. All this bogus info about bug out bags, bug out vehicles, and bug out locations is just a ton of suicidal bs as far as survival goes. Any bug out bag a person can reasonably carry will not provide enough food to last more than 60 days. We have tried this and dehydrated food is the only feasible plan one can have for lengthy time driven bugging out. Canned food is good, but extremely heavy. Dehydrated food and lifestraws will put you light years ahead of the pack{We dehydrate our own vegetables, fruits, and meats]. Vehicles will only get you killed so how do you take enough supplies to last a year or more. Well, the lowly wheel barrow works tremendously well. With or without a few homemade alterations, such as side bodies, the ‘Texas dump truck'[wheelbarrow] will carry an enormous amount of supplies and is easily hidden while we scout out an area or forage for food or the best drinking water. The wheelbarrow, in effect, is our bug out location. Whereever it is, we will not be far away.One person alone can carry a lot, a whole lot, and if you have two or more people the possibilites are almost unlimited. Make sure the inflatable tires are replaced with solid rubber if possible. We had no trouble in finding solid rubber replacement tires but if you do then get a hand pump and several tube repair kits. Garden utility wagons also work well. Even for carrying infants and small pets the wheelbarrow/garden wagon works great. Admittedly I do not live in the mountains and don’t really know how functional a wheelbarrow would be in that terrain, but it works great in the flatlands and hills. For the small amount of money invested and the positive results achieved a wheelbarrow is the way to go when shft. thanks and God bless.
When you go back to the last depressing days when we were in a survival mode, the last one the Y2K of course, before the 1970s, what had happened was you only saw this one element of survivalist, you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This is a very different one from that: you're seeing average people taking smart moves and moving in intelligent directions to prepare for the worst. (...) So survivalism in every way possible. Growing your own, self-sustaining, doing as much as you can to make it as best as you can on your own and it can happen in urban area, sub-urban area or the ex-urbans. And it also means becoming more and more tightly committed to your neighbors, your neighborhood, working together and understanding that we're all in this together and that when we help each other out that's going to be the best way forward.
Manufacturers make special kinds of heavy concrete that absorb more radiation, usually for nuclear waste storage facilities. But ultimately, you’ll need a very thick layer of concrete, not only for the walls but above and below you. It’s important to calculate how much radiation your bunker will need to absorb in the worst-case scenario you’re prepping for.
There are some weight considerations in that MREs weigh more than freeze dried food but they do have their advantages. I have a few boxes stored as part of my food storage plan because they are an easy way to get the calories you need for survival. I also have food stored in buckets, canned food and freeze-dried food. I am an equal opportunity food storage person and there is something to be said for having variety. Are MREs the the best prepper food? I don’t think there is ever a single best food for all prepper situations, but MREs are proven reliable. If our military uses them you can bet that you could find reasons to use them too. They are more expensive than other options but you don’t have to prepare anything, they even throw in the salt, pepper and a little moist towelette to wipe your face and hands when you are done. They used to come with toilet paper and chewing gum but apparently that is not part of these MREs.
This is an obvious one, but if you don’t already have it – or any other lists for that matter – it’s a good list to start with. Having a list of items you’ve got stockpiled helps you to know exactly what you’ve got and what you’re missing, which will help you to remember to buy more of what you need and to refrain from stocking up on more items you’ve already got enough of.
Above ground level, this 4,500 square-foot luxury house, located about 140 miles west of Dallas, has three bedrooms, four-and-a-half bathrooms, commercial-grade kitchen appliances, endless prairie and lake views, and even a private golf putting green. Below grade, there’s a 1,000-square-foot structure with reinforced steel walls, bunks for 12, plus a kitchen, laundry facilities, a periscope so survivors can view whatever remains on the post-apocalypse surface, and two hidden escape hatches. The bunker comes equipped with an NBC (nuclear, biological, chemical) filter system and a hydroponic plant-growing system. Six backup tanks of oxygen, as well as 10 years’ worth of emergency ready-to-eat meals, are included in the sale too.

I.N.C.H. pack: I'm Never Coming Home pack. A pack containing everything needed to walk out into the woods and never return to society. It is a heavy pack loaded with the gear needed to accomplish any wilderness task, from building shelter to gaining food, designed to allow someone to survive indefinitely in the woods. This requires skills as well as proper selection of equipment, as one can only carry so much. For example, instead of carrying food, one carries seeds, steel traps, a longbow, reel spinners and other fishing gear.[citation needed]
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
*We wanted to test the Augason Farms 30-day bucket, but due to the 2017 natural disasters driving up demand for emergency food, we couldn’t get that exact one in time for this article. Instead, Augason sent us a 1- and 2-week bucket, which together have the same food as the 30-day. We used the nutritional data from the 30-day bucket in our analysis.
The largest doomsday bunkers in the United States are not only for civilians. In 1992, a Washington Post writer by the name of Ted Gup exposed the hidden bunker at Greenbrier Resort in West Virginia. For decades the retreat of government and Presidents, the resort has a massive bunker located below the West Virginia wing complete with an auditorium large enough for the House of Representatives and a separate space for the Senate Chamber. Holding a television studio, hospital and living quarters for all members of Congress in the event of a nuclear war.  Tours are now available of the bunker to visitors of the resort.
As well as tools, stock up on basic supplies. Some plumbing fittings are good to have – pipes, joints and similar items. A couple of spools of electrical cable can be used for repairs or projects, and you can also strip and separate the cores if you need fine wire. Simple light fittings, switches and other components help too. Stock up on timber; 4×2 and plywood have a multitude of uses.
Canned meat: Get about 20 cans of assorted meats. Without refrigeration it will be hard to keep meat from spoiling, and that’s if you can get it in the first place. There are quite a few options, SPAM, Ham, Beef, Chicken, Tuna and sardines, but remember buy what you eat now. Also make sure you have a manual can opener, your electric can opener might not work.

My biggest fears our that men, particularly white men, will refuse to grow up, all the while corporations rape & pillage the earth and set working class people here and around the world against each other to their advantage. Men need physical work & activity, craft, not office life. Without that men find themselves frustrated & lash out, unable to define themselves in the world. There is a reason that handcrafted materials are so often better, homegrown food healthier.
Using resinous woods (such as pine) for interior heating and cooking fires a very bad idea. As smoke cools on its way up a chimney, flammable resins accumulate in chimney flue(s). Eventually, months or years later. when someone builds another fire (say, during a cold Winter night), those resins ignite, and you have an upside-down solid-fuel rocket engine. Flame may gush sideways out of cracks in chimneys, igniting an entire abode.

There are many schools of thought on what should be stock piled in the event of a disaster or prolonged period of social disruption or societal collapse. It is hard to say with complete authority what “The best” foods are. This will depend on a number of factors, such as storage space, number of people to be fed, availability of water for preparation, availability of a means to cook foods or heat water, and the list goes on. There are however some standards that can guide pretty much anyone in the right direction. Just be certain that whatever you store, it provides enough calories, a dietary proper balance, vitamins, minerals, and fats. Remember, a crisis has a way of creating situations that will increase your caloric requirements, and that will tax your immune system and electrolyte balance.
