We've had several requests from folks in Jackson, MS about aikido dojo near them. The neartest that I've found is a Fugakukai (Karl Geis) dojo in Starkville.
That said, there are several Hapkido dojo there that showed up on a Google search. There is also a BJJ dojo. I haven't verified that with the Gracie listings, so take it for what it's worth.
