Have ridden it once. A little elevation, few rocks, and sandy corners. Tulsa's a cool town so it's worth the trip.
Also, this is close by:

Bentonville is just a little farther.
Ended up with 24.23. Plan your route/pack your gear. There's lot's of nothing out there.
Next time out, I plan on starting/ending in Granger. There's a brewery and BBQ in town. Proper motivation to make it back alive.
