In Troy the July light hangs on past nine o'clock, sliding long and gold across the yards off Wattles Road, and that is the hour when a mowing line shows itself best. Prime Time Lawn Care and Landscape works this flat old farm plain the way it asks to be worked — mowing, trimming, edging, and the cleanups that carry a yard from thaw to freeze. Come winter the same trucks turn to plowing, shoveling and salting, so a driveway is open and gritted before the first commuter headlights swing down Long Lake Road. There is a plain pleasure in a straight stripe laid across a wide back lawn, and in a walk cleared square to its concrete corners. Whether the grass is climbing an inch a week or the air has gone still and metallic the way it does over Oakland County before snow, the work is the same promise, kept on time.
