You can spot the big peach off I-75 from a long way out, and beneath it Byron goes about its business in the flat glare of midday. Smith's LawnCare is out working in it, cutting lawns while heat shimmers off the driveways and the cicadas keep up their steady racket in the oaks. Mowing, string trimming, a sharp edge and a thorough blow-down of the pavement make up the routine, run the same way on every property. Summer scarcely lets up between May and September here, so the schedule does not either. The reward is uncomplicated: a yard that looks square from the curb when you pull in.
