NASCAR's Sprint Cup Series is at the Richmond International Raceway this weekend for Saturday's Richmond 400. Last year, Kyle Busch equaled the great Richard Petty with his third win in a row at the Richmond spring race. This year, he's shooting to join Jeff Gordon and Darrell Waltrip as the only drivers to win the same Sprint Cup race four straight seasons. The Sprint Cup Series returns to the short track for the third and final time this spring.
