Best area in Oklahoma?

I'm prejudiced to the NE, "green country" (slogan pre-dates "eco" green). The Arkansas-Verdigris River and tributaries, cutting through gently rolling hills, and full of anthropogenic lakes. Mostly civilized people, outside of Tulsa.

But there's a bit of everything in the four corners of the state. Except mountains you can ski on, but Colorado and New Mexico are next door. And no ocean. However, the prairie grasses look like ocean waves.
