Even crazier (or, at least, equally crazy) is another video I saw on Youtube a couple years ago. Two clowns wearing balaclavas and Go-Pros walked along the very edge of the trestle (sorry...old habits!) and climbed around underneath on the support beams (without tethers). At one point they even do the "one-armed dangle". It's totally insane. The RCMP said they would not pursue charges because there was nothing to charge them with.
