Summer mornings in the valley open under a low river fog that lifts around nine and leaves everything beaded and bright. Ruiz Landscaping is already out in it — mowing, trimming close around fences and posts, edging clean along the concrete, working the beds and laying mulch while the day is still cool. Yards near War Veterans Park and out through the neighborhoods all get the same handling: cut it even, finish the borders, sweep the walk before pulling away. A yard looks finished when its details are, and that is the part worth doing carefully. Lawn work in Olean and the towns that ring it.
