Down by the mill pond in Stony Brook the water slides slow past the old grist mill, and on a July morning the whole village smells of cut grass and low tide together. KC Landscaping keeps lawns across those streets — mowing, trimming, edging, and the tidy cleanups a shady, sandy-soiled north-shore yard tends to ask for. Grass here grows under big oaks and against a salt wind, which makes an even, healthy lawn something earned rather than assumed. The pleasure is all in the finish: a border cut clean along the walk, turf that looks composed beneath all that dappled light. Small streets, careful hands, nothing rushed.
