UrbanMan's reply: Prepper, I agree - fast and mobile,.....or, stationary and hidden in a well stocked safe location. About anyone with decent survival training and a modicum of preparation can survive. I've done that in small increments for training. Ten days with nothing other than a fixed blade knife, 2 one quart Army canteens and one canteen cup, a small survival kit with snare wire, para cord, matches, button compass, a lightweight poncho and a map. It sucked. I lost about ten pounds. Learned much about isolation and being bored as well. And as stoic and tough as we think we may be, humans are not made for isolation.
I think the idea is to not only survive but live with some decent standard of living. The only way to do that is to have planned ahead, prepared well, and most likely be part of a larger survival group.
I'm not advocating some type of "survival commune" living, but planning and preparing with an alike minded group of individuals and families for mutual support.
Caches are always a good idea. To support the Bug Out plan, either at or near the safe location, or along the way supporting long range movements. I have written several posts on caches. And my student Jim (from Survival Chronicles of Jim) emplaced a couple near his family cabin which is his Bug Out location.
I hope not, but cannot help but think there are people out there thinking that if a severe enough collapse comes, they will survive on their own in a minimalist fashion. Great to have those skills, but better yet to be prepare across the spectrum of needs and do so with a focused plan and a team.
