Along Detroit's old industrial corridor the buildings run long and low and the lots run wide, and snow out there is a logistics problem before it is anything else. Detroit Commercial Snow Removal treats it that way — plowing lots and drive lanes, clearing walkways and dock aprons, salting so a first shift can park and walk without thinking about it. Piles go to the corners where they will not eat parking spaces or block sightlines come February. Most of it happens in the hours nobody sees, headlights swinging across empty asphalt. By seven the lot is black and wet and the day runs as though the storm had skipped the block entirely.
