Many of the various trail maintaining clubs supporting the Appalachian Trail now employee "trail runners"...seasonal employees to continuously travel the trails, assisting hikers, training in proper low-impact camping, and serving as official/unofficial "eyes" to report any problems to the authorities.
Soo....how much money would it cost to fund a couple of "trail runners" for what, 30 weekends a year? That would be "evangelists" for the right way to wheel? And not afraid of telling somebody (and/or calling the authorities?). Maybe work thru the USFS directly, and fund a couple of folks that would actually be their employees, and under their authority (and have full authority)...
We have brainstormed/dreamed here about raising money to buy land as a group....this would just cost pennies compared to that, and might help keep UNF open.
