A driveway edge is a small thing until you see one cut right. Then the line runs sharp against the red clay and the whole yard reads as though someone meant it. Edge Control Outdoor Services works that line all over Chickamauga — mowing, trimming, edging along drives, walks and beds, and cleaning up so the concrete is bare and the grass stops where it should. Midday here in summer is bright and heavy, cicadas going in the hedgerows, and the crew keeps at it until the last pass is straight. The reward is simple and it lasts all week: a lawn with corners, and a curb you can follow with your eye.
