They do have to buy a SWA permit (or have a hunting/fishing license) to use CPW lands, however, CPW can’t charge for access to federal lands. Not much to be done there for state revenue. I do know what you speak of on the front range accessible trailheads though -it’s terrible. Unfortunately, the San Juans are getting the some level of concentrated impact from ORV users, despite the much lower population. Seems unsustainable, but the roads are county roads that cross FS and BLM lands. What can you do? Even if SxSs get banned, which they most certainly will at some point in the near future, the Overland YouTubers, Jeep badge campaign, Toyota rallies, etc have already done the hype damage.
