East Mesa resident Scott Rolfness rolls his eyes toward the heavens whenever he hears the distinctive sound that every driver in Arizona instantly recognizes: the loud ping of a rock hitting a windshield. "Again," he utters in half resignation and half disgust, but he knows exactly what to do next. Rolfness said he calls Progressive Insurance, his carrier, and heads to a Safelite glass repair shop a couple miles from his house. Safelite employees jokingly call the soft-spoken Rolfness the king of rock chips. It’s a title he might not cherish, but he readily admits it fits his experiences behind the wheel during the past year.
