TULSA, Okla. — It's time for America’s Greatest Homecoming, where seas of fans flock to Boone Pickens Stadium and fountains run orange, but what truly makes Oklahoma State University Loyal and True are the people who keep the tradition alive year after year. The OSU Spirit Riders are responsible for one of the most iconic mascots in the University's history and the Oklahoma roots that make "Bullet" so special. You know the phrase, “Here comes Bullet!” A majestic black horse races onto the field.
