There is a wind that comes up off the Niagara at Gratwick Riverside Park and runs inland across the west-side lawns, and in June it carries the smell of cut grass a long way. Apex Services WNY works in that air all season, mowing on a schedule you could set a watch by and trimming the spots a mower will never reach. The satisfaction is in the finish: a clean line of edge along the walk, no clippings left on the drive, a yard handed back better than it looked an hour before. Spring startups and autumn leaf work bookend the mowing, because grass out here is a year-long conversation rather than a summer errand. The routes run from North Tonawanda into Tonawanda, Wheatfield and Amherst.
