Hey! Another neat place to ride not too far from Moab (northwest) nearer Green River is place called Dubinky. Sand dunes, sandstone hills, fantastic riding....I don't remember the tight staying on trails requirements there....probably about 1 1/2 hours from Moab. I used to ride there about 18-20 years ago...it was always a blast in the winter. You can get there a farm exit off of I-70, south about 5-10 miles...
