Best I can do is way up in the mountains of western North Carolina. I know I've read of stuff in SC. Search the forum archives over at http://www.swordforum.com
That's where the majority of koryu jsa folks hang out. If you can't find anything in the archives, create a post like this one and sign your real name. I'd also advise including your town so that people know how close their suggestions are to you.
Remember to sign your real name. It is a rule on both forums, and one that they take seriously.
