The WARE show is bigger, is a 2 day show, and has more vendors than the Dixie Reptile Show. And run by two of the nicest promoters you can meet. I'll be there at the USARK table, and I've been to every WARE show since it launched.
I used to go to the Dixie Reptile show, but it has more of a swap meet feel than the WARE show.
