Out at Thalmann the land lies flat and open, pine flatwoods giving way to marsh, and the morning air comes in off the water already warm and full of salt. The Yard Man Inc. works this coastal Glynn County ground with mowing, edging, trimming and cleanup, on a growing season that runs long here and asks for attention most of the year. Grass under live oaks and Spanish moss grows in patches and moods, so a yard gets read shade by shade before the first pass. The pleasure is in the finish: even turf, a clean edge where the lawn meets the drive, clippings off the concrete and nothing tracking indoors. When the afternoon light comes back across the marsh grass, the place looks settled and cared for.
