The MARTA red line runs south through College Park, and on a Saturday morning you can hear a train pull out while the mowers are still warming up. Kings Economic Home Services LLC tends the yards in the brick-and-bungalow blocks near the tracks, where lots are modest and every foot of grass sits in plain view from the street. Midsummer means cutting on a tight turn — zoysia and Bermuda push hard from May onward — with edging along the walk, trimming at the steps and porch skirts, and the sidewalk cleared before the truck moves on. Small yards reward precision, because a missed corner has nowhere to hide. Done properly, the whole street reads a little brighter for it.
