This is from the work to keep the Rubicon trail open for everyone.
@Del Albright can provide even more info on this.
Friends of the Rubicon was formed to save the Rubicon when the county wanted to install a gate.
Potentially having the ability to close the trail on a whim if they wanted.
Rubicon Trail is technically a registered county road.
Friends of the Rubicon was formed and people from many organizations, clubs and individuals worked side by side to save the trail, eliminate high profile resource damaged areas and help the surrounding environment all in the name of keeping the trail open.
I have lead, helped and oversaw a few work parties on the trail over the years.
After a while they formed the Rubicon Trail Foundation as a 501.c.3 so they could collect donations, funds and other material things to help preserve the trail.
Some of the same people involved here have also helped form other Friends groups to preserve trail access in other areas.
It is a proven method that has worked.
Within this group and the others, they usually have a "Trail Boss" that is assigned to coordinate things, but no true formalized leadership hierarchy exists.
