Down along the Lynnway the lots run wide and flat, and wind off the harbor pushes snow across them in long drifting sheets. ED&M Construction and Landscape works that exposed ground when storms arrive, plowing, clearing walkways, spreading salt and sand where the gusts scour pavement bare and then bury it again. Coastal snow packs heavy, and a lot that looked finished at midnight can want another pass by three. The measure of a night is whether people can park, walk and get where they're going in the morning. Usually they can.
