Hopewell's fields still run to hedgerows, and the lawns tucked among them catch every leaf the wind decides to move. LandCare Group LLC works that boundary between the kept and the wild — cutting and edging where the grass ends, clearing leaves out of the beds each fall, spreading mulch in spring, keeping shrub lines from creeping inward. When the cold comes down the Stony Brook valley the trucks change over to plowing, hand-shoveling walks, and de-icing aprons and turnarounds. Long drives out here take a while to clear, and they get worked so a car can pull out without touching a bank. Steady upkeep in the warm months, early hours in the cold ones.
