They're really hard to find around here lately for some reason. Live ones, I mean. I have one snake who's really picky and she's driving us up the wall.
Anyway, if you don't know about this site already, it's basically the largest web portal for reptile people- [link]. I looked already and there doesn't seem to be a Wisconsin reptile show or club, but hopefully you can use it to find a local breeder or hobbyist. Good luck!
