The first thing a storm changes in Clifton is the sound: Route 46 goes quiet, and the ridge of Garret Mountain vanishes into gray. That is the hour iMoonShine Cleaning Service LLC is already out, headlights swinging down the brick streets of Botany Village while most of the city is still asleep. Snow removal here means the short steep driveways of Dutch Hill, the path from a side door to a car, the curb cut a mail carrier will need by nine. By the time the sky turns the color of milk there is black pavement where there was white, and salt laid down where the ice meant to set. A night's work that shows up as an ordinary morning — which is exactly the point.
