Yeah, I have to just repeat what Ken said. I'm new to the herp hobby in this area and have only been to the one show in Phoenix last month. That one was pretty small compared to others I have been to out east. I don't know if you made it to the Phoenix show, but there was only one vendor who specialized in bp's...everyone else who had only had a couple along with all their other herps, as if bp's were an afterthought to their collections. LOL
I don't know if the Tempe show will be the same, but I imagine it will be pretty close. Still...since you already live as close as you do, I'm sure it'll be worth the trip for you. I didn't regret driving all the way to Phoenix for the last one.
One of the vedors at the Phoenix show told me there is a much bigger, annual show held in Tucson in the fall...but since the date/location hadn't been finalized yet, she couldn't provide any specific information. I'm still watching out for that one.
