Stories in local and national media have contributed to this perception. In fact, mountain bicyclists, hikers and equestrians can and do share the trails. In multiple use settings, all users should be aware that they may encounter others. Bicyclists and other users should always anticipate others at blind corners. Faster moving riders sometimes surprise and intimidate slower moving hikers.
Uphill users are sometimes surprised by downhillers.
The more experienced the users, the less the liklihood of surprise. Like other recreationalists, more experienced cyclists can socialize new cyclists in the responsible use of off road bicycles. Always yield trail. Never spook animals. Leave no trace.
