HERPS show in OKC - anyone been?

I was checking my subscription graveyard email and noticed Josh’s Frogs was going to a show in OKC. The dates coincide with when my mom is coming up to visit, so I figured we could make a day trip of it.
The shows we have over in the Tulsa area can be walked through on a lunch break, so I’m assuming this is going to be at least a bit bigger… but I don’t see a vendor list, so it’s hard to gauge how long we’ll end up being there.
