May 9, 1971: Benny Parsons wins the Halifax County 100 at South Boston (Va.) Speedway for his first Cup victory. Bobby Isaac leads 216 of the 281 laps on the .357-mile track, but his day ends after 247 laps with engine problems. Only 12 of 28 cars are running at the end, and Parsons beats second-place Richard Petty by more than a lap.
