I would suggest Highway 83, but it seems a little out of your way if you're leaving from Tulsa. The monument rocks just south of Oakley are actually very cool, at least I thought they were worth it. If you're wanting to see some prairie, I would recommend the western part of the state expecially. Also in Oakley is a Prairie Dog Town, you honestly would have to see it to believe it, I would like to go into detail about it but you wouldn't believe me. 6-Legged Steers, prairie dogs, rattlesnakes, 8,000 pound prairie dog, etc. Honestly, if its not out of your way that is a must.
