Winter reaches Hackettstown from the northwest, over the long shoulder of Schooley's Mountain, and it usually arrives after dark. Danny International Tree Service works the hours that follow — plowing driveways, opening walkways, spreading salt on the short steep pitches that Warren County folds into so many addresses here. The reward comes at first light: pavement showing dark and clean, a car backing out without a second thought, a set of steps that won't send anyone sliding. Storms in this valley rarely fall politely, so the plan is to be out in them rather than behind them. By the thaw those driveways are only driveways again, which was the whole point.
