The coves of Lake Hartwell hold their fog past sunrise east of Martin, and then northeast Georgia turns bright and green in a hurry. CB Grading & Hauling LLC mows the lawns on those red-clay slopes — the ones that fall away toward the water and never once mow flat. Edging runs along the drives, the trimmer works around dock paths, boat trailers and retaining walls, and the walks come clean before the gate goes up. Grass grows hard here from April into September, and a yard on a weekly rotation stays a yard instead of a hillside. The best minute of the day is the look back up the slope at a finished cut.
