Gliders ride the ridge thermals above the Chemung valley all summer, and from up there the lawns of Pine City are a patchwork of greens. Turf Jockys Lawn Care Service keeps that patchwork sharp. Mowing, week by week, on time. Trimming around fence posts, mailboxes and the base of the old maples. Spring cleanup in April, leaves hauled off in October, the yard given back open and breathing. It is steady work in a valley town, and the proof of it shows from the road — and, apparently, from the sky.
