I freely admit that I'm a fan of parkour, also known as free running. Any sport that has disdain for things like gravity, danger, and man-made structures is all right in my book, especially if it results in sweet-ass videos like this. Then there's the above video, which is also awesome, but for entirely different reasons. And by "different reasons" I mean "smashed face."
Let this be today's lesson: God hates people with visors.
