Leave no trace. Control your bicycle. Always yield trail. Never scare animals. Bicyclists should know and follow applicable laws and regulations.
Bicyclists yield trail to foot travelers, both animal and human.
Joint activities can provide rider education, trail planning, volunteer trail maintenance, or just plain fun interaction. Cross-country bicycle travel off trails is not appropriate. Establish quantitative and qualitative measurement scales for impacts. Establish impact thresholds which, if reached, trigger correction or closure of the trail to bicycles. Establish a schedule for monitoring activities.
