At four in the morning Watchung Avenue is nothing but streetlight and falling white, and that is the hour this crew likes best. A and S Landscaping llc runs snow removal across Plainfield, plowing driveways and cutting walkways open while the flat ground below the First Watchung ridge is still asleep. Storms here come down off the mountain out of the northwest and lay themselves across the city block by block, and the answer never changes: get out early, push it back to the curb, salt the ice before it can set. There is real pride in a driveway that is bare and gritted by the time the porch light goes off. The whole reward is somebody stepping outside at six-thirty with keys in hand and finding nothing in the way.
