By late October the pecan trees on Glennville's side streets start letting go, and the yards under them need more than a pass with the mower. Davis Family Lawn Service cuts, edges, trims and rakes the whole of it back to green — leaves gathered, walks blown, borders re-cut where the summer softened them. These are quiet streets, the kind where a mower two blocks over is the loudest thing going on a weekday morning. A yard raked clean under a bare pecan has its own kind of order to it, plain and satisfying. When the frost finally comes to Tattnall County, the lawns here go into it tidy.
