Your post kind of got off to the wrong start - people here are REAL testy about stuff like low impact and ultra light and leave no trace and stuff and consider backpacking almost an artform or a form of meditation, a way of slippng in and out of the wilderness unseen, etc etc.

Frankly a huge number of them have absolutely no survival skills that would be of benefit in the event of total social melt down and they don't like to think about stuff like that, so no - very few people here even have food two weeks supply of water and fuel in their homes. Or a plan...

So nope - not many survivalists here...

We could use one of those vote thingys but we wouldn't get an accurate count since unprepared people wouldn't admit to it.
