Problems with Sooners continued with each successive land run; in an 1895 land run as much as half of the available land was taken by Sooners. Litigation between legitimate land-run participants and Sooners continued well into the 20th century, and eventually the United States Department of the Interior was given ultimate authority to settle the disputes. Sports In 1908, the University of Oklahoma adopted "Sooners" as the nickname of its football team, after having first tried "Rough Riders" and "Boomers". Eventually, Oklahoma became known as "The Sooner State." The school fight song is titled "Boomer Sooner". The school "mascot" is a replica of a 19th-century covered wagon, called the "Sooner Schooner." When the OU football team scores the Sooner Schooner is pulled across the field by a pair of ponies named "Boomer" and "Sooner". There are a pair of costumed mascot also named "Boomer" and "Sooner".
