You can hear the dam at South Hadley Falls from the Holyoke side when the Connecticut is running high, a steady sound sitting under everything else. MJR Landscaping works both banks of the year on the properties near it — mowing, trimming, mulch and cleanups while things grow, plowing and shoveling once they stop. The river valley keeps its own weather, throwing fog in spring and heavy wet snow in January, and the route answers to that. Drives are pushed back to their full width, walks opened to the door, and ice treated where cold air pools low along the flats. Grass in summer, pavement in winter; the property is the constant.
