My brother and I raced motox all through school and college. My brother does photography and writes for RacerXill, Transworld, and Dirt Rider. He said it was an absolute mess this past weekend. When Mcgrath was leading his heat race, the stadium was so loud with people cheering that you could hardly hear the bikes!
