West of town the ground drops into the Millstone valley, and on a summer evening the light comes down the river flat and gold between Kingston and Rocky Hill. Green Valley Lawn Care finishes its days in that light — the last mow of the afternoon, the trimmer along a fence line, the border reopened where grass has crept over a walk. Valley ground grows thick and grows fast, and it rewards a cut that arrives on time rather than when it happens to be convenient. Fall cleanups close the season out on those same properties. Princeton, Kingston, Rocky Hill, Montgomery and Franklin Park are where the trucks go.
