I am one of the "in" crowd, mainly because I don't have anywhere to go. Staying home has it's upside clearly, but I think it can't be sustained long term. Something I didn't think of until I watched the after armageddon show which you've probably seen, even after the first waves of scavengers go house to house, in the long run scavengers will still be combing through the huge junk pile of urban areas. When the supplies run out, you'd have to become a part of some kind of agricultural community. There's not space in my backyard for that. Lastly, I think Colorado would be particularly challenging given the climate and soil.
