I'm not familiar with the particulars of the single track, however I am familiar with the 4x4 routes which were closed as of November 1st and the BLM is enforcing them as such. This club and trail leader also works with the BLM on projects throughout the state, hence why it stung a little more when their trail leader was threatened with a ticket for organizing the activity.
Excerpt from their ordeal:
A couple weeks ago one of the clubs that I am a member of had scheduled a trail ride. Just an average trail ride on public lands, to enjoy "open" trails that are 100% legal to ride. There were 7 riders that showed up for this "organized" ride. There were also 2 BLM Rangers that showed up with their citation book in hand. They threatened to issue a citation to the Ride Leader if he followed through with his plans. The BLM Field Office that sent these Rangers had contacted the Ride Leader a few weeks prior and informed him that the "club" would need to apply for a permit. The Ride Leader explained that he knew the laws and regulations very well, and that he did not agree that a permit was required for a non-competitive, non-commercial, club trail ride on legal trails. Then, the night before the ride, the BLM contacted the Ride Leader again. This time telling him that they had decided a permit WAS definitely needed, but now there wasn't time for him to get one. The BLM explained that since this ride had been "organized" and advertised to the public on the club's website, it DID require a Permit. Once again, Big Brother BLM insisted that the ride could NOT take place. The morning of the ride, at the advertised trail head there were 7 riders ready for a fun day.....until 2 BLM Rangers showed up with ticket book in hand. They once again threatened to cite the Ride Leader if he followed through with his "organized" ride.
