No one knows the heartache of parking on campus better than Marv Herrington. Make no mistake, Herrington can park anywhere he likes. But as Stanford's chief of police and the person ultimately responsible for enforcing University parking rules, Herrington has seen the tears, heard the anguish and felt the pain caused by parking trauma. "It's a universal truth," he says, "no one is ever happy about parking. I'm always amazed that people get so exercised about it." (Me, too. I park in a free 40-minute green zone outside Marv's office for two hours. No ticket, no sweat.)
