Tragic and funny. Check out this story from WJR Fox 47 in Chicago about the 'Zombie Containment' attraction off Navy Pier that sank on Halloween.
Word is that some of The Zombie Containment's undead residents began popping up randomly in the days since Halloween, which led to emergency responses from the Coast Guard. When the origins of the floaters became apparent, sailors used the opportunity to run "man overboard" and CPR drills.
Maybe some of the undead will wash up on OUR shores of Lake Michigan!
