Brian Mosby isn?t your ordinary dude. When he wants to have a good time, things tend to get a little crazy. Brian recently took a walk on a tightrope, or a ?slackline? near Rio de Janeiro. The rope was strung at an altitude of 850 meters. While he carefully braved the insane gap on a rope, his assistants took some pretty awesome pictures of Brian. If there?s any way to get over your fear of heights, I doubt this is it. RFL to you Brian Mosby, you are truly one Radass dude living life to the fullest!
