I found this grasshopper in my studies at Packsaddle WMA in Western Oklahoma just North of Cheyenne, OK and the South Canadian River. But the question is... what kind of grasshopper is it?

Answer: Plains Lubber, Brachystola magna!

Initially collegues thought it was an Eastern Lubber, but I was not convinced. Much thanks to Tom A. Royer from the Department of Entomology and Plant Pathology at OK State University for his email suggestion!
