From the top of the hill in Sunset Park the harbor goes gray and the skyline stands out in the weather like it's waiting for something. Brooklyn Snow Removal is out under that sky in the middle of January, pushing lots clear, cutting walkways through the drifts, working salt into the ice at the base of every ramp and step. The streets there run steep enough that a bare sidewalk is not a cosmetic matter. By the time the buses are running again the routes are finished and the surfaces are down to pavement. Snow plowing, shoveling and ice control in Brooklyn and nearby areas.
