Winter in Mount Morris often arrives on a clipper out of the northwest — quick, dry snow that piles at the end of a driveway sometime between midnight and the alarm clock. Lawn Star LLC is out in it, plow lights sweeping across drives and lots, pushing back the banks and salting the walks so the morning belongs to whoever has to leave for work. Come spring the same trucks trade blades for mowers, and the year turns into mowing, trimming and edging across the same streets. Knowing a property in July makes plowing it in January easier: you already know where the drive really ends. That continuity is the quiet advantage of a year-round outfit in a town this size.
