Four in the morning on Ludington Street, and the lots have to be open and walkable before the first door in town unlocks. St. John Snow Management runs winters on that clock — plowing lots and drives, clearing entries and sidewalks by shovel, staying in front of a storm instead of chasing it. Escanaba receives its snow both in quantity and in installments, sometimes both in the same night. Most of the craft is timing: knowing when to make the first pass and when to come back around for the second. Nobody ever notices a lot that was cleared right, and that invisibility is exactly the standard.
