I am a member of Louisville Marine Aquarium Society that is not too far from you IMO. Many of our members live in Southern Indiana and often our meetings are held at the Falls of the Ohio in Jeffersonville at exit 0 just across the bridge from Louisville. We have very active members who travel from both Scottsburg and Santa Clause as well as Jeffersonville, New Albany, Clarksville and Sellersburg. Going north to Indianapolis would be a little closer to you where they have the Indiana Marine Aquarium Society. We have traveled to their frag swaps every year and pass Columbus on the way. One of our members is also a member there and from what I have seen and heard they have a fine club as well.
