Definitely research where youre going and make sure your wilderness survival skills are legit. Know the wildlife in the area. If there's bears, cougars, etc know how to handle them. If your near a small town and always wandering in youre going to raise suspicion. Plus, Keep in mind there are backcountry rangers that patrol certain areas. I've heard of people stumbling upon pot fields and luckily no one was around. Get on the forums at bushcraftusa and ask questions. A ton of people on there with a lot of experience and expertise. I've found Idaho, Oregon, N MN, N Cascades, Wyoming to be good but once winter starts to hit it's a hard game to play unless you have everything you need and your Bushcraft skills are tops. I'm not sure about Utah canyonlands, AZ ,ETC. but Daniel Suelo lived in caves for over a decade.
