At the foot of Seneca Lake, where Catharine Creek comes down through Watkins Glen, air off the water keeps Dix green well past the point it has any right to be. GIGLIO LANDSCAPING SERVICE mows and trims through that long season, edging along walks and drives and keeping the beds mulched and defined. Vineyard slopes climb the hills on both sides of the lake, and the lawns below them take every shape a hillside can invent. Spring cleanups pull out the leaf litter and washed-in sand; by late October all of it is on its way back down again. A cut lawn with a clean line against the pavement is worth doing right on ground this pretty.
