Moutain Biking

I've been riding ATBs for about ten years now--and hiking and backpacking since I was in diapers (I'm 31). I've never had a confrontation (except for mabye the occasional dirty look) with any other trail user in that time. Of course I always yield to all other trail users and don't fly around blind corners--and I always take out trash. Cyclists here got organized a long time ago. Volunteering to work on trails, educating their own …

…changing the situation. We've been trying to do the right thing and go through official channels to change things for a long time now. People are poaching more and more trails now, often at night, which certainly isn't going to help matters any. I don't thing a full on land war between cyclists and land managers, a la the Vancouver North Shore, would be a positive thing for anybody. What can be done? Any suggestions?
