Jonesboro softens at dusk, when the last heat lifts off the asphalt and the first porch lamps come on down the side streets. 138 LANDSCAPE LIGHTS LLC works lawns in that long southern evening and in the cooler hours on either side of it, mowing, trimming and edging until a yard reads clean from the curb. There is a particular satisfaction in a lawn finished just as the fireflies start up over it — every pass straight, every border true, the clippings cleared off the walk. Beds stay tidy and hedges stay shaped, so a house looks cared for whether you are pulling in at six or heading out at six. Around here that is the whole job: a yard that greets you before you reach the door.
