When a nor'easter swings inland the snow comes sideways off the trap-rock ledges and piles against every north-facing wall in town. Lizza Construction plows through that in Montville, opening driveways and lots, clearing the entries, salting the walks the wind keeps scouring bare. Some storms need one pass; some need the truck out three times before daylight. The reward is watching a driveway go from a blank white field to open pavement in a few minutes of steady work. By morning the town moves again, and that is the whole point of the night.
