Waterslide

I'm sure most of you have seen the waterslide video by now. I threw it in below if you need to watch again.

How awesome would this be? It brings me back to the good ole days on Lucas St with the Sponge Bob slip'n'slide...

I did some searching and found something a little more realistic with a great soundtrack.

Has anyone been to any good water parks in this area? Water Park of America? Anything good in the Dells?
