Three in the morning, a nor'easter shoving across the Sound, and the hill on Glen Street is already going white again behind the plow. Panzarino Landscaping & Masonry runs those hours — plowing drives and lots, shoveling walks and stoops down to the concrete, salting the low spots where meltwater will freeze back before daylight. Storms reach Glen Cove off the water wet and heavy, the kind that packs solid at the apron and bends whatever it lands on. The measure of a night is simple: people open the door at six and go, no shovel, no guessing, no ice at the bottom step. When the streetlights click off over the harbor the routes are clear, and the trucks head back around to check what the wind has filled in.
