Along the highway running south toward Thomasville the lots come one after another, each with a strip of grass that either says somebody is minding the place or says nobody is. GW Property Maintenance LLC minds them: mowing on schedule, edging walks and parking margins, trimming around signs, poles and fence lines, hedges kept back off the doorways. Cleanups pull leaves, limbs and drift out of the beds and off the pavement. In a growing season this long, the schedule is most of the work. Pull in on a Monday and the place looks open before anybody unlocks a door.
