I saw it a few years ago and it made me smile. Used to be a highlight of any trip to Ft. Wilderness to go to the beach and catch this.

This image really made me smile; it's just how I remember it ...
If Disney isn't planning any kind of water show - they'd be foolish not to move these over there as a nighttime draw.
