Saturday mornings near Crocker Pond start with birdsong and finish with the sound of mowers, which is about as Westminster as summer gets. A&D Mowing takes the grass in even passes, runs the trimmer along the walls and posts, and blows the clippings off the drive before pulling out. Bed edges are cut so the lawn stops in a line instead of a fray. Spring cleanups pull winter's litter out of the turf, and fall cleanups take the leaves off before rain glues them down. The reward is a yard that looks quiet, which is harder to achieve than it sounds.
