West of town the Columbia County streets run in long curves, and on a June evening every yard on the block sits at a slightly different shade of green. Neat ground has a geometry to it — mow lines parallel to the walk, trimming that matches the arc of a bed, an edge that follows the curb instead of arguing with it. That is the standard, held weekly through the stretch of the year when Bermuda puts on an inch between visits. The blowing comes last so nothing is left scattered on the drive or out in the street. On a cul-de-sac it is easy to tell which yards are on a schedule, and it is good to be one of them.
