In Oklahoma, where tornado warnings can mean the difference between life and death, there are no bigger names in storm-chasing than Val and Amy Castor, a husband-and-wife team who serve as a mobile early warning system for approaching storms. The Castors are part of a network of storm chasers who broadcast live for Oklahoma City's CBS station, getting as close as possible to pinpoint a tornado's path. Manuel Bojorquez reports on the couple who have saved lives and challenged death together for 25 years.
