OK the oak toad's range stops in SE Virginia. Which is a good thing, because if it ranged into Pennsylvania they would not be able to bring them. It's illegal to seel native PA animals at the show.
You could e-mail Glades earlier in the week before the show to make sure they are bringing what you want. BTW their next show is June 5 & 6, basically next weekend.

Don't put ice in your cooler, just a bottle of cool tap water. You just want to keep them from over heating, not freeze them.

Whatever animal you buy will come in deli cups, so as long as the cooler is big enough for the all your deli cups to fit in, you will be fine. Leave the cooler in the car. Carrying it around the show will be a pain in the *** as the hall is usually quite crowded.

Last time I went I bought an albino Woodhouse's toad for $50. Sadly it died a month later.

That lizard and snake exhibit was a traveling exhibit by Clyde Peeling. It traveled all over the country and I saw it in Boston. My vet got to work on the mamba. The last exhibit that Clyde Peeling sent out was on frogs. I saw it in Boston's Museum of Science. Here is the link to his traveling exhibits - http://www.reptiland.com/exhibit.html
