I live on a lake and can catch enough fish to survive awhile to supplement my preps but others are going to be doing the same, coupled with the fact there is a clan of trash a mile away that would dynamite every fish in the lake. The herd of semi tame neighborhood deer would disappear overnight. I could go on a friends ranch and shoot a feral hog but its a two hour round trip and fuel will be like liquid gold. Plus how are you going to process a stinking feral hog with no ice and refrigeration?
I'd need to get a water purifier to drink lake water. It gets hotter'n fuck here in summer and thats with A/C. I like to camp but not forever. Life would suck.
