South of town the Connecticut River loops back on itself at the Oxbow, and the Meadows lie flat and wide open — ground where fog stands at dawn and the wind crosses with nothing to slow it. Eco Valley Lawn Care works both halves of the Northampton year out there and up in the neighborhoods. Green months: mowing, trimming and edging on a regular round, with a clearing pass at each end of the season. Cold months: driveways plowed, lots opened, walkways shoveled, sand and salt laid down where the ice glazes over. Valley storms come in heavy and wet off the river, and a drive opened at four in the morning is the reason a workday starts on time.
