Twin City came by its name honestly: two towns, Graymont and Summit, that agreed to become one. Allgreen Services mows both halves and the roads leading out of them, keeping Emanuel County lawns cut through a growing season that opens in March and runs deep into November. The sandy ground here drains fast, so grass answers a hot week by browning and a wet one by exploding, and the trick is showing up either way. Edged at the walk, trimmed along the fence line, the concrete swept clear — a short list that never changes. What changes is the light, from the white glare of July to the low gold of a fall afternoon.
