Yes pretty prairie, some small mesa's, salt plains, rolling hills, lakes, rivers, mountain foot hills (no real mountians though) OK has such an abundance of different geography, it is often overlooked. I am not native to this state, but truly consider it home.
I agree Oklahoma is versatile! My DH is an Okie (Shawnee). I lived there about 12 years and wouldn't have a problem moving back. I loved the country and the people.

You both would love the weather!!
Hawaii was even worse. Pretty, but not places I'd want to live. I don't like to sweat when I'm just sitting still.
