Lawns that run down to Lake Chemung keep their own weather — fog off the water most mornings, dew that lingers past breakfast, ground that stays softer than it does a mile inland. Cottons Landscape LLC mows those slopes and the flat yards inland alike, holding a steady cut, trimming close to seawalls, dock posts and garden beds. Waterfront grass comes on fast and thick in July and wants a sharp blade more than anything else. The satisfaction is standing back at the road afterward and seeing the whole run to the shoreline as one unbroken sweep of green. Around Howell, that is the shape of a summer well kept.
