This Sunday (10/11) from 8 am to 2 pm Niles Canyon will be closed to vehicle traffic. This is a great opportunity to visit the Canyon as a bicyclist or pedestrian.
This is being done in conjunction with the plan to create a pedestrian/bicycle trail. There will be displays about the proposed trail along the route and free Niles Canyon Railway rides.
This sounds like a real fun event. You can read more and sign up here:
