September evenings in New Lenox smell like cut grass and somebody's grill, and the light goes amber right around seven. Luke's Lawn Care finishes its days inside that window — mowing, trimming around posts and beds, edging the walk, and blowing the clippings off the drive before leaving. One street at a time, one yard finished properly before the next one starts. The growing season on this prairie is generous right up until it abruptly is not, so every week in it gets used. A tidy yard at dusk is a quiet sort of good news.
