David Ragan, driver of the No. 6 AAA Ford Fusion and Raybestos Rookie of the Year contender, has a great deal of experience at Atlanta Motor Speedway, but most of it has come on the quarter-mile Legends track. Ragan, who grew up in Unadilla, Ga., is scheduled to start 38th in Sunday’s Kobalt 500. He spoke about coming back to his home track and how he plans on getting to the front tomorrow.
