I'm down in Mustang (SW Oklahoma City), and Ataru lives in Claremore (close to Tulsa if I remember correctly). What are you wanting to test for your tune?
I wish there were stuff going on, but we have events on the occasion here rather than weekly. How long are you going to be in Tulsa, Tom? It doesn't look like there's really anything going on at Hallett (the only racing circuit in OK if I'm not mistaken) for a while.
