I could be wrong here, but I believe the only tanks usually at shows are the vision style and maybe some other higher quality cages. Don't think you normally see cheaper tanks (10g) etc at shows. Freedom Breeders is on the vendor list, so maybe they'll have some racks for sale?
Speaking of Freedom Breeders...If they're listed does that mean NERD will have some snakes there for sale? *crosses fingers*
I wish RDR was going to be thereunless he's under a different name on the vendor list...
