My plan for an TEOTWAWKI is pretty simple - do my best to live like people who are living TEOTWAWKI now. By this I mean, if you dropped me off in some remote impoverished village with no toilets, doctors, electricity, what have you, life would be hard. I might not make it. But people certainly do. We're just very used to a modern lifestyle. Humans don't need much to keep the a heart beating. Think simpler. If you really think you'll have good water access and a reasonable fuel supply (talking wood or other naturals here) buy yourself 500 lbs of dried stuff (beans, grains, etc) per person and have fun.
