For those of you who have ridden the San Bernardino mountains and love it as much as I do; read on...
Our local club (Big Bear Trail Riders
http://home.socal.rr.com/bbtr/ ) has a "spin-off" called "Americans for Forest Access" (http://www.forestaccess.org/).
Our local strategy is to UNITE everyone we can (e.g. bike riders, horse riders, quad riders, jeepers, indian tribes!, etc.) under a non-motorcyle "brand name" to respond to local trail closures.
The last Forestry trail closure meeting I attended was somewhat upset when a member of an indigenous indian tribe delivered a notice that their constitutional rights would be violated by trail access restrictions to their sacred religous sites. It was great! They're on board with us now.
My point is that localized or even nationalized organizations, that unify common interests among diverse "trail-users" deserve support, even if you don't like jeepers, quaders, whatever. We're just out to stop trail closures, within reason. We'll sort who uses what, when and how...later.
The "battle" needs fighting at several levels by the strongest force we can assemble. Allies can make the difference.
Our "homefront" battle is to respond to the trail closure advocates who commission geologists and biologists reporting endangered plants on our trails. If you have the money, it's easy to do, even though arguably a blatant exploitation of endangered species legislation.
However, if there's no "in kind" reponse, we're screwed. Our challenge is learning the rules of engagement and building a warchest to counter "in kind" what happens in the "trenches".
Not enough comes from interested sponsors and memberships. Some comes from proceeds of club sponsored enduros. More support is needed. If you cherish this riding area, join up.
