March storms in Greenfield come in heavy and wet, the kind that bends the maples over Federal Street and turns to slush by noon. Ginger Cat Sealcoating plows through them — driveways and lots pushed clear, walkways opened, de-icer down where the melt will refreeze after dark. Wet snow is the harder kind: it weighs, it packs, and it has to be moved before the temperature drops out from under it. Downtown lots and residential drives alike get taken down to the surface, with the piles set somewhere they won't block a sightline. By the time the sun works through, the pavement is already drying.
