A route through Catoosa County covers ground — ridge to ridge, one valley road to the next, with Ringgold sitting in the middle of it. Georgia Lawn Ranger runs that circuit week by week, mowing, trimming, edging and clearing every walk and driveway before moving on to the next stop. Midday sun flattens the color out of everything, but the mowing stripes still show once the light swings back around. There is a rhythm to a long day of yards: arrive, cut, clean, go. By the time the trailer ramp goes up for the last time, a good many places look better than they did that morning.
