At three in the morning during a storm, Atlantic Avenue belongs to the plows. Mancuso Snow Plowing & Lawn Maintenance is out in it, driveways opened, walkways cleared, lots pushed back past the curb line, salt down before the wind off the beach can glaze everything over. Snow on a barrier island arrives wet and heavy and is rarely polite about it; it packs against bumpers and drifts into every gap between houses. There is nothing quite like the sight in the headlights of a drive going from white to black asphalt in a single pass. Atlantic City, Ventnor and Margate get worked through the night.
