No kidding about the MTB's. Even 20 years ago, I was nearly run down by a mountain biker on the Freeman Creek Trail. There was also much OHV activity then, and trails were very dusty.
This area was where I set my Personal Best of remoteness: 48 hours without seeing or hearing another person or vehicle. It is probably more populated these days.
Some fairly current resources for the area:
