Here's a map of my standard loop over Mt Orient. The stretch along Heatherstone Brook is nice. The total distance is 11.5-12 miles - if this is too short, we could add a smaller loop at the north end, or exit by continuing along Heatherstone Brook farther downstream.
The two maps are the same except for size: the larger one shows the contours better.
My house is #23 on Wildwood Lane, roughly across the street from Wildwood Elementary School in Amherst - see the map! Tel. 549-5804
