But, though not absolute zero regulations, most of southern Utah is wide open, un-populated, gorgeous and is open BLM land, with only token regulations. And of course for the best backpacking areas in Colorado, Wyoming, Norther AZ, etc, etc, no permits are required, but there are mild regulations posted here and there. Like no bikes in the wilderness areas, stuff like that.
California, on the other hand, seems to be silly-highly-regulated, but I suppose that's simply because of the higher density of use.
