The Larkin trail runs its old railroad grade across Middlebury, straight and level through country that is anything but. Fine Line Landscaping takes its cue from that idea — a mow with true lines, trimming that follows the shape of a bed, an edge that holds where lawn meets stone. September is the trail's best month and the lawn's as well, with cool nights bringing the green back after August. Grass grown on a Connecticut hillside never cuts itself even; it takes a pass in the right direction and a little patience. What is left behind is a yard with a drawn edge and nothing out of place.
