My son, several of his friends and I plan on being there on Sunday (which is the only day it's held . . . ). You'll find most kinds of non-venomous / non-giant herps. You'll find frogs, insects, arachnids, boas, pythons, colubrids, lizards and turtles. You _won't_ find any mammals other than eyes-closed pinkies and fuzzies - and so far, I haven't seen any ASF among them. (I would consider buying a bunch of rat fuzzies to foster to my own breeders . . . .) You'll find supplies, frozen food, tee shirts, caging and toys for big & little kids.
And you'll find a metric crap-ton of folks who share your interests - and perhaps a friend or two!
