Where exactly does the wind go sweeping down the plain?

Oklahoma is celebrating its centennial. For those of you who do not know, Oklahoma is a state famous for at one time being a big patch of "Indian Territory." Glad they did away with that! The Trail of Tears? Emo.

Apparently they became a state in 1907. In 1957 they celebrated 50 years. Part of the celebration was burying a car. Guess what? They are going to unearth it this year. Aren't you excited? Wooooo!
