Meerkat has a valid point that should not be ignored.
Too often people romanticize "survival". If I have to live in the dirt, i would just as soon go down swinging early on. The 'ol bod probably isn't up to it any longer - living rough for extended periods, that is.
I imagine there will be some gruesome times prior to a total collapse like some talk about. Fascism, totalitarianism, communism... all those "ism's" with martial law, internment camps, people disappearing, being labeled a "enemies of the state" and "terrorists", not being allowed to buy or sell without approval. That sort of stuff. Its already in the works. No stopping it now without a civil war.
Maybe my grandchildren and your children will have to live in a teepee once the dust settles, but it won't be my generation.
Hmmm... maybe there is a reason I saved my 16' teepee all these years... I lived in it the first summer ('75) here in Maine on the homestead while I was building my solar house. Loved it!
Got it way back in the hippie days (summer of love) when I had a fully legal mining claim up in Evergreen, Colorado... the frustrated forest service couldn't make me take it down. (Dug a hole with pick and shovel, "salted" it with gold-flecked porphyry ore from Ouray/Telluride and had the ore assay certificate and claim map right there). There were 16 peop- uh... miners camped on the "commune"-claim. More than one way to skin a government cat!
Maybe I'll dig it out and pitch it for all my little grand-nieces & nephews ... sure is pretty in the moonlight with the cook-fire glowing through and the smoke curling up thru the poles.
