"It's Bristol, baby." Richard Childress talks about the storied Bristol Motor Speedway in Bristol, Tennessee and recalls racing there for the first time in 1969—there were just 15,000 seats in the grandstand and drivers raced on an asphalt track. Today, the NASCAR short track is America's fourth-largest sports venue and seats up to 162,000 fans. Childress says he's enjoyed some of his best finishes there, and his grandsons, drivers Austin and Ty Dillon, share their thoughts on the track.
