Saturday morning on Oglethorpe Highway, trailers rattling toward the day's first stop — that is the sound of a Hinesville weekend getting started. Bennett Lawn Services is somewhere in that line, headed out to mow, edge, trim the fence rows and clear the cuttings off the walk. Coastal Georgia grass keeps its own schedule and does not much care what else anybody had planned. So the route runs, week after week, and the yards along it stay level and legible. Hinesville, Flemington and the roads out past them.
