I sometimes wonder if I would have relatives in the US, alot of people did immigrate from here in the mid and late 1800's
Luckliy, one of my cousins did all the work for me. Because of it, I can trace our family's American roots right down to the moment my first ancestor came here. It was in 1638, in Jennings Creek Virginia. So we've been here longer than the US was a nation, hehe.
I do feel that if society falls permanently, we'd see a warlord type deal spring up. Would have to really. That said, my plan would be to work WITH said warlord in a live and let live scenario, where we provide food, services, etc. for added protection and other trade goods. I'm not looking to rush towards it, but I'm not remote enough to be unseen forever, so eventually, bound to happen.
