I don't think the government can control or track 350,000,000 million people. So technology is worthless. About only 250,000 troops can't control the U.S. population and look and the government can't even control immigration. So don't worry.
Perhaps, but if they have put live cameras on ALL of the Forest service roads, and gradually closed off the little unused ones so that only the main dirt/gravel roads were accessible, they could patrol it and find you quite easily. Of course, currently it's NOT illegal to be there, and NOT illegal to have a weapon up there.....but....
It appears to me that they got the cameras installed last year. Certainly none of us knew that they could track every Soviet Sub (and whales) for that matter, in all of the worlds oceans no matter where they went, as far back as the 70's. They have the sky's blanketed with spy satellites, we really don't know with what.
