Gates lies flat where Black Creek runs west of Rochester, and its neighborhoods are laid out in tidy rectangles that show off a straight mowing line beautifully. Clean Cut Lawn Services works them — mowing, edging along walks and drives, trimming out the fence lines, and clearing the yard in spring and again when the leaves come down. Saturday mornings the whole street can hear the season, and the finished lawns are the ones with a crisp border where turf meets concrete. That edge is the difference between a lawn that has been cut and a lawn that has been taken care of. Gates and the towns beside it get the second kind.
