At three in the morning US-31 out toward Acme is empty and the headlights show nothing but snow moving sideways. JD Snowplowing keeps those hours through a Grand Traverse winter — plowing driveways and lots, opening walkways, laying salt where the ice sets up hard. In a heavy season the nights blur together, and the truck runs until the route is finished and then starts over when the next band comes ashore. What lasts is the simple picture of a clean driveway at sunrise and somebody getting to work on time. That is worth losing sleep over.
