I've never heard of that happening. Here are some other things you can check into. The Jungle Queen, take a water taxi ($10/pp per day), or google everglades excurions, they used to offer airboat rides. The Jungle Queen has been in business for years, it takes you to a Seminole indian village and they have a bar-b-que there, plus alligator wrestling. The water taxi will take you through the intracoastal (be sure to go to Shooters-great drinks, good food and Charlie's Crab is just a couple of doors down-great food). If they still have the airboat rides in the Everglades, that is a blast. Best wishes!
