Griggstown sits where the Delaware and Raritan Canal runs alongside the Millstone River, and on autumn afternoons the towpath becomes a corridor of gold leaves and slow brown water. Gary W. DiMeglio Landscape Services keeps lawns in this old canal village, a stretch of Somerset County where the bridge tender's house and the lock still mark the water's edge. Fall here means leaves drifting in by the bushel, and the season's work is clearing them away, bringing the grass down short and setting each yard up to rest through the cold months. A finished Griggstown lawn looks as unhurried and orderly as the canal itself.
