August afternoons in Boulder build their weather out east, a shelf of cloud stacking over the plains while the Flatirons still hold full sun. A J Lawn Services works the hours before that arrives, mowing and trimming through the flat blocks of Table Mesa while the grass is still cool enough to cut clean. Edges get their own pass — the straight line where turf meets concrete, kept sharp week after week. Clippings are cleared off the walk before the crew moves on, so the only sign anyone came is a lawn that looks freshly combed. Spring and fall cleanups bookend the season, and in between it is simply the steady return, the same route, the same care.
