I just found out about this yesterday and thought I would share for any forum members in Chicagoland. I know there's a few of us.

Expo is twice a month at the DuPage County Fairgrounds (Wheaton IL). I was told by the owner of a local pet store yesterday that there's usually a herp & exotic animal vet that will do free wellness exams for turtles if you bring your I have also been told this a great place to get a sweet deal on driftwood or corkbark.
If anyone from this forum is interested in going, PM me and I'd love to meet you out there.
