Welcome to the forum. I don't know of any Arkansas clubs in that area. The only other one I'm familiar with is in northwest Arkansas and their primary focus is freshwater. You're welcome to attend any meetings we have. We try to move around the state throughout the year for our meetings.
There are no clubs in the area (this and dallas are the closes forums) and so far I've only met commercial tanks (doctors offices and such) only one at someone's home. Looking forward to the frag meething.
