This valley is built on limestone, and you can see it turn up all over Lyons in flagstone walks and stone edging worn smooth by decades of feet. Pretty Stone Landscape and Design Inc works around those lines all year — mowing and trimming so turf never creeps where it shouldn't, edging clean against every path, then clearing snow off the same walks once winter arrives. Snow is honest that way: it hides a lawn but reveals every line you've bothered to keep. A path scraped down to its own surface after a storm is a small, exact kind of good work. Warm months or cold, the aim doesn't move — nothing blurred, nothing overgrown, nothing buried.
