South of town the freight planes ease down toward the Alliance runways all day, and the roads underneath them reach a dozen different small towns before dark. Any City Lawn Care L.L.C. runs a route through that country out of Northlake — mowing, edging, trimming along fence lines and mailbox posts, then blowing the drives and walks clean before the trailer ramp goes back up. Some stops are a quarter acre on a new street; some are a long front pasture edge on a farm-to-market road. The address changes and the finish does not. Weekly and biweekly service keeps warm-season grass from ever getting out ahead of itself.
