Erin sits up in the hills north of Elmira, where the little lake at Park Station holds its morning mist until the sun clears the ridge. Turf Pros Lawn Care runs the mowing rounds through those hollows and hillside lots, with weekly cutting, trimming, edging along the drives, fertilizing, and cleanups in spring and fall. Southern Tier yards tilt more often than they lie flat, and a slope mown in even lines takes some doing. That is where the pride sits, in a hillside lawn that reads smooth all the way from the bottom of the driveway. When the leaves come down through these woods in late October, they are gone before the ground freezes underneath them.
