The Shawangunk Kill runs cold and clear along the town's western edge, and the hills above Ulsterville hold their frost a good hour longer than the valley floor. M & S Landscaping and Construction LLC works up and down that ground in both directions — mowing, trimming, edging and seasonal cleanups through the green months, then plowing, shoveling and salting once the cold owns the mornings. Grass grows thick off this valley soil, so the lines come up sharp when it is cut on time. The snow comes wet and heavy and rewards an early start. Between the two, the calendar stays full and the properties stay in shape.
