Boone Pickens Stadium (previously known as Lewis Field) has been home to the Oklahoma State University Cowboys football team in rudimentary form since 1913, and as a complete stadium since 1920. The facility is the oldest football stadium in the Big 12 Conference but was left largely neglected and enjoyed only modest renovations throughout its near-century of existence.
With the resurgence of Cowboy football sparked by the 2001 victory over the Oklahoma Sooners in the annual Bedlam Series game and the subsequent 2002 Houston Bowl season, interest grew for a major overhaul of Lewis Field. An ambitious fund-raising project for the renovation dubbed "The Next Level" became the flagship effort of the Oklahoma State athletic department.
Officially the capacity is 60,218.(Wikipedia)
