You got the who, still waiting for the how.

To impose a permit/quota system, you will need a commitment from FS and a whole lot of patrolling volunteers. Without that, it is a waste of time.

I do not see how they can get the resources required from a valley with such a small population where the minimum distance to the trailheads is in excess of 60 miles. Most volunteers I have patrolled with do so close to home to minimize expenses.
