There is a rhythm to a summer week in this town — the courthouse square quiet by mid-afternoon, the heat stacking up, thunder somewhere off to the west that may or may not deliver. Calhoun Lawn Care, LLC moves through it on a route: mowing, edging, trimming, clearing the clippings, week in and week out from the first flush of spring until the grass finally gives up in the fall. Carrying the town's own name means the yards are, in a sense, the sign. Bermuda cut at the right height and edged along a straight walk is a plain and durable kind of beautiful. That is the whole ambition, repeated well.
