Mark Barlow Sensei of Akayama Ryu in Foley, Alabama should be running classes in Shodokan Aikido as far as I am aware.
He is one of the heads of Akayama Ryu Jujutsu and is also ranked in Shodokan Aikido by one the Technical Director of the Japan Aikido Association, Shihan Tetsuro Nariyama. Here is the web address - www.akayamaryu.com
. His contact info is on there as well.
On a related note, I will be teaching a seminar in Shodokan Aikido at their Winter Camp on the 16th and 17th January. You are very welcome to attend to get an idea of our training method.
Mark is online here somewhere on Aikiweb. I'll PM him to check out this thread.
I hope you find what you are looking for.
