There is !
Art, I'm with ya man. And thanks for the link Jabber. I think we can do something:
Keep your eyes open for the Bubbas and their trucks. If they stray off trail, rearrange rocks / trees to suit them, do burn-outs or bust berms, take a crap in the stream, whatever ... REPORT THEM! I started keeping a notepad and pen in the cubby for just such purposes. Take their plate number, brief description or vehicle and offense, and date of occurrence, and hand off to your nearest ranger.
Most of us now have dig cameras with us (or cell phones) when wheeling. We could start taking photos of offenders and posting them on this and other web sites, or at the regional ranger office or trailhead. Might have to be careful if the 4x4 has a gun rack, but seems like a do-able thing to me.
It would be great to start posting signs at trailheads regarding trail etiquette and that violaters WILL be reported. We shouldn't have to, but some folks need more explanation than others.
Do you know if trails can be "adopted" by 4x groups? I know they do that in some urban areas for trash control, but I was thinking about trail maintenance and repair. I'm not a gifted worker type, but would be happy to help if it keeps trails open and 4x'ers reasonably well respected. We could always do this ad-hoc ... set a date, post a message, and show up. I'm up for it.
btw - it's not just 4x'ers, but ATV'ers, bikers, mountain bikes, horse riders, campers, and even hikers. So many folks just don't seem to think about what they are doing when out on the trails.
