Multi use works here. Whiel there may be some inconsiderate MTB's I beieve they are the minority. A little tolerance of others is all tht is required. Trails should be available to all user-groups. Trails that are designated for hikers only disregrad the fact that some people due to bad knees, cannot hike, and therefore, are denied the beauty of those trails.
Most cyclists are happy to share the trails.
Seems that in places where there are conflicts, it is a minority of hikers who want to prohibit other users. Ads and publicise for days to help maintain and rebuild trails. Skewed by extreme users. One way trail is useless, nobody uses this as it goes uphill. Parks Service is doing a good job.
