Up on Chestnut Ridge, spring shows up two weeks late and leaves early, and everybody in Farmington plans around it. Mountain top lawns takes the season as it comes — mowing the wide lots along the National Road, trimming tight to the fence line and the rock, edging drives that run off Route 40 straight into the trees. At this elevation the grass stays cool and thick well into August, when the valley farms have already gone tan. Fall arrives fast off the Laurel ridges and the work turns to leaves, cleared off the lawns from Chalk Hill down toward Ohiopyle before the first wet snow flattens them. There is real satisfaction in a mountain yard cut square against all that unruly forest.
