Down in Franklin County the summer gets serious early — heat with a weight to it, cicadas going all afternoon, oak shade that people plan their whole day around. BH Mowing LLC works the lawns through it, mowing on a steady turn, trimming close along fences and foundations, edging drives and walks and clearing the cuttings off the concrete. Grass here jumps after a Big Muddy thunderstorm and then sulks through a dry August, and the schedule bends to both moods. Six in the evening, low sun laid across a finished yard, every line where it should be: that is the picture the day is aimed at. Fall brings the leaves and the cleanups, and then the mowers go quiet until the ground warms again.
