In January the light coming off the Savannah River is thin and gold, container ships slide upriver beneath the Talmadge Bridge, and the grass is finally resting. Vista's Lawncare LLC spends those quieter weeks on cleanup — hauling off leaves and fallen limbs, cutting back what sprawled all summer, getting yards ready for the first hard push of March. When the season turns, it is mowing, edging and trimming again on a regular round. A clear view from the porch out to the street begins with ground that is kept. Every yard has one good angle, and the work is making the rest of it match.
