I believe last year was the first time that expo came here. I haven't been to that one, but I've been to repticon when it used to come here, and reptilian nation a few years ago both at the south florida fair grounds. They were both great, lots of turtles and tortoises that I remember. I imagine a lot of the same vendors go regardless of who's running the expo.
Here are some pics I took from reptilian nation. Turns out I went February of last year. To my knowledge these were local vendors so likely to go to the scales expo also.
