Currently I have left it loosely based so that we can find a place based on where people interested are located. What I am trying to do right is gauge interest in such an event. To my knowledge, there are few if any gatherings in this area.
As far as a possible location. Mt Petit Jean in Arkansas has been suggested. Photostock has certainly evolved from what Bill Schwab has told me. I mentioned it because I went this year and enjoyed it a lot. It would be nice to have something for this region of the country.
