South of the river the streets around Potter Park go quiet early on a snowy night, and for a long while the only sound is a blade scraping down to blacktop. WoodWorkz Lawn Care and Snow Removal works those hours — plowing drives and lots, shoveling walks and porch steps, salting the slope where a car has to stop. By the time the woods along the water are light again, the route is finished and the day can start on schedule. Lansing takes its snow in long installments rather than one grand event, so the job is really about being dependable in the middle of the night, over and over. A clear driveway at six in the morning is a small thing that makes everything after it easier.
