Last Saturday, a friend and I were coming down the Motorway and got pasted up by a couple of dirt bikes (motorized). I reported the incident to the CNF office. The Trails Manager told me I could report violations like this, to Forest Dispatch at 1-619-557-5262. She said they'd answer the phone with "Monte Vista", but it is the correct number to call and report violations. I know others here have seen dirt bikes on this trail. The trail has enough broken up rock without these guys making it worse. When you see motorcycles, call in a report so CNF knows there is a problem up there.
