The Hockanum leaves Vernon quietly and runs west across the county — low and green in August, rimmed with ice by January, the town's own argument that a year has two halves. Yin Yang Professional Services, LLC works both of them. Warm months: cutting grass, trimming close, keeping the borders sharp, and running the cleanups that carry a property from one season into the next. Cold months: plowing, shoveling the walks, and treating ice underneath before anybody steps on it. The balance is the business — grass for half the year, snow for the other, the same property looked after either way.
