A nor'easter announces itself over Pleasantville hours ahead — the wind swings around, the gulls move inland, and the Black Horse Pike goes quiet in a way it never does otherwise. Full Effect Solutions works those nights. Plows on the driveways and lots, shovels on the walks and the steps, salt on the places that glaze over first this close to the water, then another pass when the storm keeps adding to it. Shore snow is heavy and wet and it sets fast, so the difference between clearing at two in the morning and clearing at eight is the difference between snow and a slab. The measure of the night is simple: pavement, and people getting where they are going.
