I would add just a few things though, if you use creamer in your coffee add a few bottles of the powdered version, some dried fruits or a couple large bags of trail mix, pie fillings in a few fruit varieties (awesome in oats!), crackers are great for kids who won’t eat a tuna, spam or other canned meat sandwich but they may be willing to eat “lunchables” DIY of course!, and other all in one items like spaghetti O’s, canned stew, canned ravioli, and ramen. It may not be the healthiest solutions but if you need these items you will be exceptionally grateful you have them!
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.
At a minimum, a good framing hammer, hand saw or hacksaw, medium prybar, axe, shovel, vise grips, screwdrivers, fixed blade general purpose knife, small mechanics kit with wrenches, can of all-purpose lube, sturdy cordage (paracord or accessory line) and duct tape. Ensure you have an adequate wrench or similar tool that can shut off water and gas valves in and around your home.
After 9/11, my dad filled a duffel bag with some energy bars, a couple gallons of water, some penicillin, and a map. Amid scaremongering headlines about imminent anthrax and “dirty bomb” attacks in the city, he wanted to have some supplies on hand in case we needed to get out of Brooklyn fast. Were he to assemble such a bag today, he’d likely stumble on a number of companies promising a more wholesale brand of disaster preparedness: a box full of shelf-stable freeze-dried meals, to be revived from their dessicated state with the addition of boiled water.
