The third stop of the California ProKart Challenge brought the teams, competitors and families to the Buttonwillow Raceway Park on April 10-11. It was a 180-degree flip in terms of weather conditions from the first weekend back in February, with the perfect weather for the record-breaking 160 drivers on hand competing in the Superkarts! USA regional event in Buttonwillow, California. The end of the event marked the halfway point of the championship chase, with six of the 11 class winners sweeping the action around the 7/10-mile course as drivers positioned themselves closer to their title hopes.
