Snow reaches Addison on a west wind, usually hours after the last shift has clocked out along Fullerton Avenue. Beverly Companies works that gap, plowing lots and drive aisles, opening the aprons in front of loading docks, and putting salt down on the glaze that follows a Midwest freeze. Dock lights and amber beacons make their own weather out there at three in the morning, exhaust steaming, the scrape of a blade carrying two blocks in the cold. By the time the first cars turn in at dawn, the lanes are open and the stripes show through the wet. The work gets done in the dark so the morning can go on exactly as usual.
