Barrington rides the hills on the east side of Keuka Lake, where vineyard rows comb the slopes and hardly a lawn sits level. C&O Property Management mows those grades, keeps the beds mulched, and cuts the edges by hand where the pitch is too steep for anything else. Fog sits on the water below until the sun burns it off around nine, and the first cut of the day is usually done by then. Autumn means clearing leaves off yards that fall away toward the lake before the rain packs them flat. A tidy piece of ground between the vines and the water is a small thing, done exactly.
