Some neighborhoods learn a business by its day. THURSDAYS Lawn Care runs on exactly that kind of weekly beat across Castle Rock — mowers off the trailer mid-morning, the route moving street to street while runners work the trails above Philip S. Miller Park and the afternoon buildup starts stacking over the foothills. Mowing, edging, trimming, and cleanups at the ends of the season, done in the same order at the same pace until a yard falls into a pattern you can read from the sidewalk. By evening the deck is washed down and a dozen lawns are sending that just-cut smell through open windows. Castle Rock, and out toward Castle Pines, Lone Tree and Parker.
