Twenty-five miles west of here, Lake Michigan decides what kind of night Grand Rapids is going to have. The bands come ashore and stack up over Alpine and Walker, and six inches can pile on one street while the next one over stays bare pavement. GrindStone Lawn and Snow Services runs against that — plowing driveways and lots, cutting a clear path along the walks, and spreading salt on the glaze that follows a thaw. The hours belong to nobody: two in the morning, four in the morning, headlights and the scrape of steel on concrete. By the time the coffee is on, the drive is open and the day is allowed to start.
