From Rio Communities the crosses on Tomé Hill catch the sun before anything else does. Blue Sky Pools and Spas is usually out by then, mowers down, working the cool end of a Valencia County morning. Lawn care in this valley is a weekly bargain with heat and wind: cut on time, trim the corners, take the clippings, come back. Done that way, a yard holds its shape all summer instead of losing it in August. And a straight, crisp edge along a driveway is a quietly satisfying thing to leave behind.
