Oklahoma is a geographically diverse state, with mountains, plains and prairies, forests, and marshes, and is a major producer of agriculture, natural gas, and oil. Located on what was once the Wild West frontier, Oklahoma retains both its cowboy culture and Native American influences, with over 25 languages still spoken in the state, as well as the headquarters of 39 tribes and nations. Oklahoma also contains more miles of the historic Route 66 than any other state.
