Late August smells like cut hay, and the meadows go tan while the yards in town hang onto their green. Big Horse Lawn Care works both sides of that line — mowing lawns on a schedule, edging drives and walks, trimming the fence rows where the pasture keeps trying to come back over. The ground holds a mower track, so the passes get laid straight and the trimmings get blown off the concrete before anybody leaves. There is a plain kind of pride in pulling out of a drive and seeing the whole place squared up behind you. Clarksville and the farms around it get the same treatment.
