Late August, and the open ground west of Bessemer goes from scorched to green again in the space of one good week of rain. Hunter Turf and Field works at that scale — wide acreage and playing surfaces where a mower runs long straight lengths and the stripes come out clean enough to sight down. Big turf has its own arithmetic: the turn at the end of the pass, the trimmed border where grass meets fence, the corners no wide deck will ever reach. Bringing a whole field up to one even color is a satisfying thing to stand and look at when the light goes low. Fields, large lots and yards around Bessemer and the towns nearby keep the season busy.
