Spring in Johnstown starts at the edges — the last gray crust of snow lingering on the north side of a fence long after the middle of the yard has gone green. Cornerstones services treats those margins as carefully as the open ground: the wide passes with the mower, then trimming tight to posts, meters and downspouts, edging until the driveway shows a clean line where grass meets concrete. On the plains a lawn's shape is what the eye reads first, and shape is made at the borders. Beds cleaned out, clippings gone, walks blown off — a small, orderly result at the close of an afternoon.
