From the upper streets of Crystal Valley Ranch on a clear morning, Pikes Peak sits pale and enormous on the southern horizon while the sprinklers are still ticking. Crystal Valley Lawn Care starts its rounds in that hour, when the grass is cool and cuts clean. Mowing, edging along the walks, trimming the fence lines, clearing the clippings — a short list, repeated faithfully, which is most of what a lawn ever wants. Castle Rock yards are carved out of dry country, so every green one is a small deliberate act. Carrying them through a long bright summer is worth doing carefully.
