Good idea, BUT...
I signed and am 100 percent behind keeping and expanding access. BUT, there is an elephant in the room that we have to acknowledge - noisy and irresponsible riders and quaders. There are just too many idiots riding out there with exhausts and behaviours at best suited for race and closed courses. I know I'm preaching to the choir here (mostly), but there are way more people who object to this behaviour than there are petition signers for open trails, so we are doomed to more and more closures.
We were out at a local off road area in the fall, stopped for a break, and a handful of screaming competition 2 strokes went past - we all looked at each other and someone said "no wonder everyone hates us".
