well as much as i understand and agree, i live in gang territory, and there's no way in hell I'm staying home if SHTF.
i live pretty close to the Angeles forest, which has acres upon acres of land to hunt and live, although i think your right, once everybody gets the idea, even as vast as it is, may become crowded and uninhabitable.
a man vs wild may be what it comes down to, and I'm well prepared to eat anything to survive, although this region there's a lot to hunt besides bear and deer, like: rabbit, squirrel, mice, etc. bugs n grubs being very, very far down my menu LOL.
i just think when roaming gangs are around, citys will have the most provisions to plunder, being it store or house. even if one has an arsenal and a food supply to last a lifetime, if 8 r 9 guys come at you, it only takes one bullet before all that becomes theirs. and me, personally, id rather be in the protection of the forest, than have my house surrounded by thugs. i mean what would i do at that point? the only option would be fight or die.
