Then a few years later, my friend and I did a week-long driving trip around the south, going from Nashville to New Orleans to Houston to Dallas/Fort Worth to Caddo Valley, Ark. where I left my transmission (long story for another time), and back to Nashville. I'm pretty sure I drove through Texarkana, which is only about a quarter inch from Oklahoma on the map.
So I had two perfectly-good opportunities to set foot in Oklahoma, and I flubbed them both. Oh, well... Next time I have an opportunity to visit, I'll snap it up. Although perhaps I should learn more about it first -- the only thing I know off the top of my head is that it's "where the wind comes sweeping down the plains."
