At four in the morning Cermak Road is empty and white and the streetlights turn the snow blue. MMaintenance+ is out in it, plowing drives, clearing walks, cutting through the ridge the city plow throws across the end of every Berwyn driveway. Winter arrives here on a west wind with nothing to slow it down, and the work is to be finished before the first commuter reaches for a coat. Snow removal is simple to describe and hard to do well: bare pavement, clean corners, salt where ice wants to set. The payoff comes at sunrise, when a whole block can leave on time.
