Give me a museum and I'll fill it. (Picasso) Give me a forum ...
No way am I self sufficient. Having said that, I could go a month without leaving the apartment and have enough food/water for that period of time - or longer. During hurricane season, we fill some 18 gallon tubs with water for flushing our 1 gpf toilet. Stores EMPTY the shelves before every storm or after a tsunami warning. We have (supposedly) 7 days of food on the islands. I think I can defend my apartment. Other than that, YMMV.
