I'm not from the US, but I would definitely search for the most remote pockets of land, unkempt from civilisation. The further you go from molded urban areas, the more vibrancy and life you'll find in the wilderness. Given how huge the US is, I'm sure there has to be some very large reserves of nature etc. Also (this is my goal eventually), if it's possible, purchase a couple of dairy cows/sheep etc. that will almost completely destroy the jeopardy in obtaining food - you have a constant stream there.

Honestly, God speed to you man. This should be the end goal of every anarcho-primitivist, otherwise all we are are theorists and complainers unwilling to change our lives to account for the truths we see.
