By September the nights turn sharp on the Tug Hill side of Martinsburg, and you can feel the season counting itself down in the grass. Lopez's Lawn Care Service makes those last weeks count — mowing, trimming, edging, leaf cleanup, and the fall work that puts a yard to bed before real snow reaches Lewis County. The maples along the back roads go red early up here, and a lawn raked clean beneath them looks twice as green. Every cut in a short northern season is worth doing carefully, because there are not many of them. Homes around Martinsburg, Lowville, Turin, Port Leyden and Constableville are on the list.
