Mad Guys Ride The Largest Urban Zip-Line In The World

Mad guys ride the largest and most insane urban zip-line in the world

Video: This is the largest urban zip-line ride in the world -- and it must be the most insane too. Watch these guys zip down a 3000m line placed on top of a 213m building in Panama City. Then -- half way through it and as if this weren't scary enough on its own -- they let go and dive with their parachutes. Madness.
