Don't worry, it's a fake -- unless someone had a pet -- it's a diamond back and they don't grow naturally in Michigan (neither do copperheads BTW).. the real thing you have to look out for is pets. Lots of "IDIOTS" like to keep exotic and often venomous snakes as pets then release them or they get away. That is what I would worry 'bout if I did worry about them. Saw a show on PBS from Chicago Animal Control. Some criminally stupid fool sold 40 Gabon vipers (very very deadly) at an exotic pet show. They found one in a garage in suburban Chicago.. some kids were playing with it. Could have ended badly for sure! It's not like a Chicago Hospital keeps that kind of anti-venom around I wouldn't think.
