water slide with a double on it?!!!!

This maybe old but the latest Racer X has an article about Pastrana's backyard playground... foam pits, buses to jump etc. But this best is a home made slip-n-slide that goes down what looks like mountain and has double jumps on it! There's a couple of pics of him about 4 fee off the ground. lol.
Anyone who doesn't attempt a backflip has to take a trip on it and its affectionately known as a "slip-n-bleed".

I won't ruin the whole article but imagine what a bus looks like trying to clear a gap jump?!!! :)
