Blue tarp surfing for a Subaru ad

A few months ago, I had a gig where I was skating on top of a parking garage in downtown Los Angeles. Hey, I've done that before. But, this time, I was skating inside this big blue tarp. It's called blue tarp surfing. I tried to explain it to my friends and family but they all looked at me like I was crazy. The ad hasn't come out yet, but I finally found a picture that shows the filming of that ad and the "blue tarp surfing."
