minty, no, it wasn't common knowledge when I was there. My assumption would have been that Disney did all it could to reduce danger to its guests (though this would usually involve roller coasters and so on), and would warn of any danger. Isn't that pretty much what you'd expect of the operator of any public attraction?
I wouldn't be surprised if Floridans know all about it, but I'm not one, and neither was the family from Nebraska.
