In the hierarchy of extreme sport douchebaginess I put rollerblading at the top. Maybe because I’m a purist that believes that Rollerblades are meant for playing drunken street hockey, or maybe it’s because every weekend I walk out of my building and my neighborhood looks like an X-Games rally. Either way, I’d like to thank whoever installed this sign next to the railing in the video, and I strongly encourage every city to do the same.
