Wolverine Lake curls through its village in Oakland County, and the streets curl with it, short lots, docks at the ends of yards, water showing between the houses. Green Thumb Garden Services keeps those lawns mowed, trimmed and edged, and tends the beds that make a small lakeside yard feel finished. When winter arrives off the water the same routes turn to plowing and shoveling, opening drives and walks and salting the slick spots. Lakeside lots leave little room to work, which makes a neat job matter more, not less. Morning on a cleared street, the lake steaming under the cold, is a fair reason to be up early.
