Tulsa's pretty rad. The Ozarks are in Oklahoma too, actually. Sorry you got a ticket: Pay attention and slow down.
The state is full of small-town cops who want to throw their weight around, but they're harmless if you play their game and (sadly) if you're the right color. That's another important consideration for potential applicants.
God, yes. I have colleagues who will not leave the interstate when driving through certain states.
