By the time the fair sets up on the Carroll County fairgrounds, the mowing season has one strong stretch left in it. MRR SERVICES LLC. works Carrollton lawns straight through that stretch — mowing, edging, trimming and clearing the leaves as the oaks begin to let go. Fall cuts are the prettiest of the year: cool air, low sun, and lines that hold their shape for a week and a half. Then the yards go quiet until spring, and the routine picks back up with the first warm rain. In town or out on the county roads, the finish is the same.
