These guys made this video in Colorado Springs. One of them, Joey Lobeck, is a member of this site. We admit to not knowing a lot about parkour or free running, but it is entertaining. And there is no denying the athletic ability of the participants.
Dante Grazioli, who is in the video and was involved in its production had this to say: "Well well well... The time has come. We tried for the best clips and production we could just for you guys, the creation of this video was some of the longest, fun, and most excruciating times of our lives."
