Now this looks pretty damn fun! Apparently its some type of water propulsion system that allows the rider to fly (tethered to a jet ski) or swim underwater as fast as a fish.
Amazing!
(sorry about the crappy song in the video)

Ok, that does look fun 
The only thing I have to add is a suggestion that people direct link to Youtube for videos; going through that page’s, well…crap…to be able to see the video, which was streamng from Youtube, was annoying, lol!
We had some people doing that the other day while we were canoeing, looked like fun.
OK, looks like fun and there’s a place not too far away. I’ll check it out.
