Flowery Branch still keeps its old railroad depot at the center of town, and the trains going by measure out the afternoons. Acosta Lawn Maintenance LLC works the yards around it, mowing in long even passes and edging the walks until the concrete shows a clean gray line. Summer here arrives humid and green and asks for a steady week-to-week rhythm rather than heroics. The reward is small and real: a lawn that reads as cared for from the street, with nothing left behind but the smell of cut grass.
