On the south end of town the streets run out toward Cheyenne Mountain State Park, and the yards along them catch the mountain's cool air by early evening. JR's Lawn Services LLC. mows and maintains that stretch — level cuts across open front lawns, edges cut in where turf meets drive, the trim line held tight along fences and mailbox posts. Grass in this corner of Colorado Springs comes on in sudden bursts after a wet spell and then waits, so the schedule stays flexible and the blades stay sharp. Clippings blown back off the sidewalk, gates shut, everything left square. A quiet Sunday street with every lawn cut is a fine way to finish a week.
