STOP YELLING, I don't live in a bubble, your right people live are from different walks of life, and a sign won't fix that if someone can't read English, doesn't know what a "no swimming" symbol means, and has no idea what an alligator looks like or does; so as I've stated numerous times at this point a sign is only as good as the person interpreting and understanding it. Next, at some point people will have to decide what is common knowledge and what isn't. I personally believe that gators in lakes are common knowledge especially in Florida. Furthermore, being in a semi-wildlife environment means to be that wildlife could be present and some of those may be dangerous. Additionally, I take "no swimming" symbols to means stay out of the water entirely feet and all, and depending on what report you go by the child could have been between ankle deep (unknown if child's or adult ankle) to 1-2 feet deep in the water. That child was in the water and shouldn't have been. The definition of swimming will need to be determined as well, and I've already stated my opinion on the matter. Next, since you seem full of adding things I haven't said, I haven't called anyone stupid, and I didn't say anything about not believing a parent. I'm stating this is a tragic accident and blame is with no one, and unless we want to live in a world that is plastered with warnings about every tiny little potential threat then we need to use our brains and realize nothing is ever 100% safe and risk exists in everything we do.
