I have never vended a show but the worst show I've been to is Repticon Charlotte. And it's every time not just one bad experience. There is barely any diversity, not many people attend so it seems most vendors leave a lot at home. I won't be back because I live half way between Charlotte and Columbia SC and can just attend that show. Columbia Repticon is really nice, but the best show I've ever attended was the Myrtle Beach Reptile Expo. Last year was the first year they put it on and it was awesome. There were a lot of big names (BHB, Greg Graziani, a few others), a huge selection, a great set up. If I were a vendor this is a show I would vend.
