I attended several Midwest Herpetological Society Conferences during the mid nineties and I seem to recall a vendor from Iowa exhibiting and selling these. He was obviously breeding them and displayed adults and hatchlings. I do not recall his name or who he was. Does anyone know and is anyone else working with these (by now)?
