The good hour in a Dacula June comes late, when the heat finally breaks and fireflies lift out of the grass along the treeline. Hunt's Lawn Service is often still out then, finishing the last yard on the route — mowing, trimming, edging, and clearing the drive before the light goes. Grass in this part of Gwinnett grows fastest in exactly the weeks it is hardest to work, so the days run long. There is something satisfying about that final pass at dusk, the concrete clean and the mower lines still readable in low sun. Then the lights come on and tomorrow's route begins.
