Come evening the light goes long and gold up the valley, and the lawns in the neighborhoods toward Rossville and Fort Oglethorpe show every ridge and hollow in their grass. CityGreen Services works those close-set yards — mowing, edging along walks and drives, trimming around mailboxes and fence posts, then clearing the concrete before the trailer gate closes. Small lots reward exactness; one straight edge along a sidewalk reads from the far end of the street. Beds get mulched, shrubs get shaped, and in November the leaves come up before they mat down and smother the grass. This is city-adjacent country, five minutes from the Tennessee line, where a yard is seen every day by everyone who drives past.
