Yeah, I've honestly been meaning to get my pistol liscense (or whatever I would need) just to have a gun in case of "choas".
Really though I'd just pack my backpack full of my gear and head into the wilderness. I (think I) could survive out there pretty well with just my knife, tent, and other stuff I have. Knowledge is the most useful tool, I've tried to learn trapping and hunting and wilderness farming techniques as best I can. Though I still have a lot of learning to do.
Anyways, I've thought about this a lot. I could write an essay on the subject. But that is a short part of my thoughts.
