It's a new, fun twist on riding that will balance their hard work. If you see trash on a ride, pick it up - especially the energy bar wrappers and inner tubes that give mountain bikers a bad name. Be courteous at the trailhead. Don't crank the Black Sabbath until you're headed home. Learn trailbuilding from the pros.
Patrols assist, educate and inform to help keep trails open.
Dazed and confused hikers really appreciate your help. Write a letter to the editor of your local newspaper explaining why you love mountain biking and why continued trail access is important. Once per ride, stop and chat with a hiker or horseback rider. We are all part of the trail community and need to get along. Go for a hike on your favorite mountain biking trail.
