Two in the morning by Main Memorial Park, the pond frozen flat, the gazebo wearing four inches and more still falling — Clifton Avenue belongs to the plows. M & K Snowplowing, Inc. runs the route: driveways opened, aprons cut back square, walks and steps shoveled, salt down before the melt can refreeze. A cleared drive at dawn is a small thing that changes somebody's whole morning. The trucks go back out while the storm keeps going, because one pass is rarely the deal. Snow ends, pavement is bare, and that is the receipt.
