That was really cool and looked like so much fun. Were they pumping the water uphill and then back onto the tarp back into the pond?

Looks like fun but also a really good way to get hurt really bad or sued.

have you seen their other video:

I have a ramp in my front yard that's a slip n slide. It's a blast for those days that the lake is too busy! Not nearly as crazy as those but who else can run out their front door and hit a slip n slide that shoots them into the lake? Hahttp://m.youtube.com/watch?v=SHY54ifVjO8

Ha we totally did this, started with the winch and then moved to the tube and jet ski. Soooo Fun!
