August evenings above Lake Lillinonah come with long shadows on the hillsides and the smell of cut grass hanging in the warm air. E&B Lawn Care Services spends its summer on those Newtown slopes — mowing, hand trimming, edge work and the cleanups that open and close the season. Hill lots do not cut themselves flat: the mower has to work across the grade, the trimmer has to follow the ledge and the wall, and the final pass has to be laid so the whole yard reads as one surface. It takes longer that way, and it looks it. A property finished at dusk, edges sharp and clippings gone, is a good place to end a day.
