For example, have you considered the need for feminine products?  What about canes, walkers, and manually operated wheelchairs?  Pets need food, crates, and toys to keep them occupied while the rest of family members are recovering from chaos.  It will be impossible to cover every contingency but be aware of what those needs are now then prioritize those that you deem most important.
You can figure 25-30 years storage life for hard red wheat, stored at 60 degrees in a 55 gallon drum, using 1 pound of dry ice to drive out the oxygen (wait 24hrs for the dry ice to “melt” before sealing the drum). 400 pounds of wheat per drum equals 400 man-days of calories, and costs you about $100. Fill 3-4 barrels. It’s Cheap insurance. Add a barrel of Winter Rye for variety. Add a barrel of oats. Then a couple barrels of WHITE rice, and 2-3 barrels of pinto beans. (You need the beans to balance what’s missing from the grains. The beans may be harder to rehydrate after 10-12 years without a pressure cooker, but then you just grind up the dried beans, and bake them in your bread.) For around $1000, you can be prepared to feed your family for close to a decade, if you also garden, keep chickens, and have fruit trees and bushes. Honey is way too expensive to store on a dollar/calorie basis, but consider bee keeping. A drum takes up LESS than 2’X2’. And they stack nicely, at 33” tall. In a 2’X10′ strip along a basement wall, you can have 10 barrels with 4000 pounds of food. Hang a peg board in front of it, and you’ve got very useful space. If you can’t spare that much space in your basement, to protect the lives of your family, think Venezuela .
as a contractor that provided service for another contractor that constructed in-ground pools the first thing I would do is drill some shallow wells in the area and see what your water level underground is. I ran into a few of these underground shelters built in the cold war period that were filled within a few feet of the top. a death trap for any child who finds its entrance. good clue if your home has a sump pump the water table may be high enough to think twice of the underground shelter.
This country is one of the safest in the world. We have no killer animals. We don’t have earthquakes. There are no major tsunamis. We don’t really have to prep for a huge natural disaster – and there’s very little you could do to prepare for a nuclear event even if you wanted to – so we prep more pragmatically. Suppose you lose your job and money’s an issue. Or the electrical grid goes out and the food chain goes down and all of a sudden every man and his dog is arguing over a bag of sugar. Do you have your own supplies? Do you have the means to cook? And what about keeping warm – could you make a fire? Some of us buy food through an app; groceries are delivered to our front doors. Do people know how to survive without electricity?
Coffee and Tea. I am a dedicated coffee drinker and hate the thought of a coffeeless existence! One pound vacuum sealed bricks are the most convenient way to store coffee, they stack well or can be kept in plastic totes efficiently. Tea is another good source of caffeine, and I love a cold glass of iced tea on a hot day. Remember that in a true crisis, you may have to maintain 24 hour watch, and caffeine is a big help in this.
This past September, Wise Company’s products proved lifesaving in a very urgent sense: Strapped for rations following the double whammy of Harvey in Texas and Irma in South Florida, FEMA placed an order for 2 million servings of food to relieve Maria’s victims in Puerto Rico. On a typical day, though, its selection of 72-hour, one-week, and one-month survival kits, packaged in boxes that can easily fit under a bed, seems more geared toward everyday Americans looking to prepare for the unknown.
