While the death of this child is tragic, and a horrible way to die, personally I cannot blame Disney World.
We need to be realistic. Disney World is built on swampland. It is an alligators natural habitat.
They are going to get into that lagoon no matter how diligently DW tries to keep up with it. If they don't get in via canals, they will walk across the land.
I'm sorry, but "no swimming" in my mind means don't go into the water.
If there's a no swimming sign, it's either because the water is polluted, unsafe, or there's danger in there. It means they don't want you in the water, not just technically swimming.
Is it definitive that there was nowhere at DW warnings of alligators? I would bet there are other dangerous animals that get into there. Wild boar come to mind. Should there be signs for all eventualities?
Unfortunately, DW is not a "magical place" When it was wondered at "how could this happen at DW?", it's a reminder to me that sometimes people just don't want to use common sense caution.
Florida and alligators. Who would have thought? Have we become so detached from nature that we rely totally on others or corporations to tell us therein lies monsters?
If you go in the ocean at the beach, you risk jellyfish, or sharks. Sometimes jellyfish and sharks are where there are no signs.
Personally, I have never looked at a canal, river or body of water in florida without thinking an alligator is in there. Haven't we read enough stories about poodles eaten for lunch in the middle of a golfing community to realize they are there?
