There is so much Hollywood thinking at this site that I think "survivalists" will be the first to die off post SHTF. Skills is not the deciding factor, per se. Time is the largest liability and calories second. They can be impacted by skills but the game of survival is all about time and calories.Here is the thing, to successfully live from a backpack, you don't need lots, and lots of gear and stuff. You need skills. You need to be the type who can forage food, hunt, fish, trap,and walk the Appalachian train end to end with just thier pack. Those types will do just fine, because they can thrive where everyone else starves. Remember, the wilderness is a place most people think one needs to be rescued form, not thrive in. Because of that, most people will be afraid to go there. If you have the skills, you will be just fine. Now I am off to memorize another page of Botany in a day.
