The Cheyenne Frontier Days is the world's largest outdoor rodeo, the "Daddy of 'em All", which takes place in late July alongside a parade and a carnival, attracting around 300 000 spectators every year. This museum housed in the festival premises pays glorious tribute to this event which has taken place since 1897. The museum is also home to a collection of old wagons, carts and carriages, as well as costumes, documents and other objects relating to the history of the West and and to the world of the rodeo in general.
