Three in the morning in the valley, and the only lights moving are the ones on the plow. A1 Snow Plowing works the steep pitches Naugatuck is built on — the streets that climb straight up from the river while Route 8 runs quiet and white below. Driveways get opened down to the pavement, walks get cut wide enough for a mailbag, and salt goes down before the first commuter reaches for a scraper. There is a particular satisfaction in a stretch of curb cleared so completely that the storm starts to look like a rumor. By the time the valley turns gray with daylight, the borough can simply leave for work.
