Downtown, in the blocks north of Monroe, the loading docks and back lots have to be open before the first delivery truck swings in off the street. Mighty's Landscape Services plows them, stacks the snow well clear of the corners, shovels the entries and door pans, and salts the aprons where meltwater sheets out and refreezes. A Grand Rapids storm coming off the lake can drop three inches between shifts, so the route runs on the clock instead of on the forecast. Concrete downtown holds its cold long after the air has given up, and treating for that is half the trade. The best sign of a night done right is a lot that nobody thinks about twice.
