A February storm in Plainfield usually starts politely and turns serious somewhere around midnight, and by then Park Avenue is a single set of tire tracks under the lamps. JR SNOW PRO does snow work and nothing else — plowing, clearing walks and steps, and laying down salt before the day's melt can freeze back after dark. There is a rhythm to a long night: push, turn, stack it where it will not block anyone's sightline, move to the next drive. Daybreak is the accounting. Bare pavement, salted, shovel marks squared off at the edges, and the whole city getting itself to work as though nothing had happened.
