The Scary Monster (106-mile) is a challenging mountainous course leaving from Mendocino College, traveling south along Old River Road to Hopland, then up Mountain House Rd to Yorkville, then north through scenic Anderson Valley and Flynn Creek Rd. to Comptche and then back to Mendocino College via Orr Springs Rd.  Great food, full SAG vehicle support and a great barbacue at the end of the ride.

A gravel bike is recommended for the Scary and Hairy rides.
