Morrow is a college town folded into the south metro — Clayton State's ground slopes down toward its little lake, and on a still evening music carries out of Spivey Hall. Dunn's Landscaping works the streets around all that, where loblolly shade and Georgia sun split most yards straight down the middle. The mowing is set on a rhythm the grass can be counted on to keep, and trimming handles fence corners, meter boxes and trunks. Edges cut along the sidewalk make the concrete look wider than it did an hour before. Nothing about the work announces itself, and the block is better for it by dark.
