Thought this was a good one to jump in on as my first post. The dojo accessibility in OKC is actually quite good. There are quite a few of Karl Geis'former students around teaching aikido (Jiyushinkai and Fugakukai), and there are several aikikai dojos also.
If you were standing at the state capitol building in downtown okc, most of the area dojos are easily within a 30 minute or so drive.
I have visited many of the dojos around okc but have practiced aikido only at Shobu Aiki dojo and Tenshinkai dojo. I have practiced judo at schools in okc and Norman.
