Water made this town — the Morris Canal came through Dover on its long haul over the Highlands, and the line it took is still written into the street names. Pacific Lawn Sprinklers Tenafly NJ works on the green that water leaves behind, tending lawns through a Morris County summer when a July afternoon can bleach a south-facing yard by Thursday while the shaded half stays lush. Mowing, trimming, edging, and the seasonal tidying that keeps a lawn even from one property line to the other. The good afternoons are the ones where you finish, walk out to the curb and the whole yard reads as a single piece of ground instead of four different ones. Dover asks for that kind of attention; on these hills the soil dries and drinks at different speeds within a single lot.
