Where to tube in OK?

Haven't taken my tube out almost at all and I'm wanting to really break it in. I've been to the Mountain Fork and blue river in SE ok but would like to explore some where new in the state this weekend. Anyone have a suggestion as to where I might pack up on a whim to go fish and float on a river? Not looking for any specific fish, I just wanna wing it.

Thanks!

Well, it's not a river but I've been thinking about taking mine up to American Horse or Watonga Lake since most of the stuff in eastern Okla is still junked up,

Duncan city lakes are excellent places to tube!!
