there is not much in the way of good long rifle shows in the deep south.
Bama,
I used to attend the "indoor rendezvous" that are so popular up north....Kalamazoo, Connor Prairie, Green Bay, Effingham, etc. I thought about organizing one in the Memphis area, but was afraid the startup costs would be prohibitive for a single individual and it might run at a loss for a couple of years.
However, the location is ideal and could easily draw from Southern IL, KY, Alabama, Arkansas, MO, MS, and LA. Getting vendors to commit is another problem, as well as building rental, marketing and advertising, etc.
There is a Civil War show held here every year that is well attended, but nothing for long rifles.
