I ended up going and it was nice. Kind of medium sized 10-15 vendors almost all with live animals. Some dealers only had short supplies, I know they ran out of crickets pretty quick (which did not affect me). A good mix of animals but very few dart frogs which is one of the things I was looking for. I was told the show in Wheaton that is on the 15th is way bigger.
