Snakes is another reason why I do not do Florida's water where I can not see.
There was a little catch phrase in camp scouts camping in Orlando they used to tell us.
"If you can not see, you shall not be" .
It basically meant if you couldn't see that part of water that you were in or wanting to get in, you shouldn't be there.
What scares me most about Florida's water is the brain eating disease that goes unrecognized by many but has killed several people here. Esp Lakes, and Springs are dangerous to swim in besides the animals.
You just always take a chance getting in the natural bodies of water in Florida.
