I'm not sure. I do not know where you found that info. I was born and raised in Chicago and moved about 4 years ago. Last I saw you could not keep ANY Poisonous reptiles. (however you do see the loophole there). No such thing as poisonous. I hope you're right and Boiga are a great species. I used to sit up at night and watch mine for hours. (yes, I had them when I lived in IL). Where I reside now I can pick up copperheads all day long. Still haven't found the rattlesnake species we are supposed to have though. Bill at www.snakemuseum.com has CBB Boiga.
