The first train out of Morristown leaves in the dark, and on a snow morning the whole town is doing arithmetic about whether the driveway will let them make it. D and D Landscape Professionals plows for that arithmetic — out ahead of the commute, blade down on residential drives and lot entrances, walks shoveled and treated so nobody's first step of the day lands on ice. Storms here like to finish overnight and leave a wind-crusted lip at the end of every driveway; clearing that apron is half the work and all of the difference. Salt goes where the shade will hold the cold, not merely where it looks tidy. Then the truck moves on, and somewhere a car pulls out clean onto Morris Street with time to spare.
