I watched the news report at the article, one sees on the slide, that is indeed, a patch of snow where one sees that white.
Maybe that's where he got stuck. I'd have to see the sled, was it one of these one sits in, I can see how that could be dangerous.
In the meantime, there were probably plenty of little hills he could have had plenty of fun sliding down; but no, they had to go to a water slide!
These Florida kids probably didn't know about the park, or too much. So, it's clear to see where that leads. Someone suggested it.
If there were steps leading up to the top of the slide, I'd probably not even want to walk those in wintertime.
