The first cut of the year is a small event. Somewhere in March the Bermuda pushes green up through the winter tan, the dogwoods open along the older Tucker streets, and the mowers come out for a season that will not quit until October. Thornton Advantage Lawn Care LLC. opens that season and carries it — mowing, edging, string trimming, clearing walks and drives, and full cleanups at either end of the year. Georgia hands out a long calendar and a lot of growth; the work is keeping pace with it, week by week. There is a plain satisfaction in the last pass of a job, when the lines run straight and the concrete is bare.
