Montana resident here - I'd much rather the BLM own the land than private entities. Private entities shut down access for not only motorized vehicles and hunting, but bicyclists, hikers, and horse riders. Even grandfathered trails which are supposed to remain open and accessible are illegally shut down, sometimes with nasty traps (like wires strung across the trail and chest or neck height).

Not to mention, the BLM maintains those trails and the surrounding land. The forest service does not (it will close trails instead of making changes which make them safe for the riders and the land), and the private entities certainly do not.

Some of the public land being sold (which also occurred under the Bush administration, as an aside) is right next to public parks, where lots of wild animals and other fragile ecosystems are in place. It would suck to watch the land around Yellowstone national park strip-mined for a few ounces of gold.
