smooth greens are much harder to find i don;t know about there but in ontario u need a permit, rough greens are supposed to be hard to take care of in captivity but wiht proper care they should be hardy theres a great book called the basic care of rough green snakes by philippe de vosjoli it has alot of useful info. good luck if u decide to get a rough or smooth green snake

post some pics if u buy one
