With all due respect for the FR preppers here, in a “Mad Max” future your survival will be contingent on membership in a powerful tribe. I’m all for having supplies for survival through a natural or man made disaster with a duration of weeks to a month or two but beyond that people will need to band together, cooperate and rebuild a civilization. Truly, no man is an island.I strongly suggest that you don't cast your lot with those whose guiding principle is "To each according to his needs. From each according to his ability".
