One of NASCAR's oldest continuously-operating race tracks is running this weekend- Martinsville Speedway in Virginia. The first NASCAR-sanctioned race at Martinsville was held back in 1948. It
actually started as a dirt track, but was paved in 1955. Fifty-six different drivers have won pole qualifying positions in NASCAR's top division over the years. For Sunday's race, Hendrick Motorsports driver Kasey Kahne will be on the pole.
