Dude, i have a bunch of friends who do stuff like that, right now they're even on "vacation" in the alps, living on a mountain and they don't even have a tent or a stove, just sleeping bags, clothing, survival meals, knife, lighter, etc...
that's exactly what survivorman does except he whines about it and plays his annoying harmonica all the time!
And do you honestly think that everyone is carrying survival equipment, like a tent, a sleepingbag, firestarter, etc? most people start of with nothing and are very poorly adapted to surviving in the environment they're travelling through...
just to say; how many of you freeriders are prepared to spend a night out on the mountain?
i bet most of them don't even have a survivalblanket or knife to start out with.....
