The Sooner Schooner is the official mascot of the sports teams of the University of Oklahoma Sooners. Pulled by two white ponies named Boomer and Sooner, it is a scaled-down replica of the Conestoga wagon used by settlers of the Oklahoma Territory around the time of the Land Run of 1889. Its name comes from the common term for such wagons ("prairie schooners") and the name for settlers who sneaked into the Territory before it was officially opened for settlement ("Sooners").
