The working waterfront doesn't get a snow day — boats come in when they come in, and the lots and aprons along the harbor have to be passable at whatever hour that turns out to be. PDL Enterprises plows on that clock in Gloucester, opening lots and drives, cutting access to doors and gates, and shoveling the walkways a blade can't touch. Sand and salt go down where meltwater refreezes overnight. Wet snow off the Atlantic is heavy and it arrives sideways, so the passes get timed to the storm instead of to a calendar. Two in the morning with plow lights on the water — that's the shape of the work.
