Dorset laid its sidewalks in marble, and on a clear winter afternoon the village green looks like something set down whole and then left alone. Keyes Landscaping LLC keeps that ground working — plow and shovel through the cold months, scraping down so the stone is not hiding under a crust of ice. When the year turns it becomes mowing, trimming and edging, with cleanups bracketing the growing season at both ends. Mountains close in on three sides here, and weather that begins as rain down in the valley often finishes as snow up on the green. Serving Dorset and its neighboring towns.
