After midnight the lots along Ridgedale Avenue are empty and lit orange, and that is exactly when the plowing gets done. Calles Brothers Construction LLC runs its Morristown snow work on the night shift — pushing wide aisles across parking lots, opening fire lanes and entrances, salting the places where tires would otherwise pack everything into ice by seven. Storms come up the coast and over the ridges with no regard for the calendar, so the trucks stage early and stay out until the last pass. Door approaches and sidewalks get cleared by hand, because a plow cannot do the last ten feet that actually matter. When the doors open in the morning, nothing about the night should be visible except bare blacktop.
