Question about land, as it relates to bugging out
I am curious about a legal aspect of bugging out. Let's say that someone takes a couple of weeks off of work, and decides to do a dry run, and roughs it in a remote location.
If one is standing at a point on the earth's surface that is inside the U.S., and that point is not in a municipal/county/state/federal park or forest, nor in an Indian reservation, nor in a military base, nor on private property, then what is the official designation of the land that contains that point? Second, what are the legal ramifications for living on such land for an indefinite period of time?
