There is a green in this city that comes from living beside all that water. Rivercrest Lawn Care mows through the long light of a Niagara Falls July, working the blocks above the upper river where the maples of DeVeaux Woods throw shade halfway across the street by four o'clock. Mowing, trimming, edging and the cleanups that bookend the growing months add up to a yard that looks like somebody chose it rather than simply owned it. The last pass is the one that matters: a straight line where turf meets walk, cut sharp enough to set a level on. Then the mower goes quiet, the clippings smell like the whole summer at once, and the lawn holds that shape until the next visit.
