By the third week of July the cicadas out past the hayfields are loud enough to hear over an engine, and the heat sits on Chattahoochee County like a flat hand. B3 Yardworx LLC works straight through it — mowing, string trimming, edging, and clearing the cuttings from drives and walks in Cusseta and out along the county roads. Summer here means grass that comes back before you have finished the block, so the route keeps moving and the yards stay ahead of it. Late in the afternoon, when a thunderhead stacks up west toward the river, the last yard of the day gets the same cut as the first. Then the rain arrives and starts the whole thing over.
