Another comment said it, but that's basically land protected from most use, with some exceptions that are more akin to our national park system, right? I'm talking more about BLM lands in the west, or national forests in the east. Also, there are states with significant public lands holdings that are in the same spirit.

With our public lands, I can usually go to them anytime I want, I don't have to reserve anything. I can park my car, I can get out, and I can begin just walking into the woods or grasslands, sometimes on trail, sometimes off. I can basically camp wherever I want in many of these places. If there's a stream, I can fly fish. If it's hunting season, I can hunt. I can basically disappear into a place that feels wild for a bit.
