Notice what went on this last weekend in the Grand Stair case Monument? The law took pics of the riders, machines, and license plates. But they were on an established route used back in the 1800's, which to there knowledge was legal. No off road riding was done.
This has been a piece of crap since BC had it set aside. If you want to see it you walk or ride a hay burner. I imagine you would need to pick up after the horse and pack it out with you.
