Watch these crazy guys zip-line down a 700 ft. tall building in beautiful Panama City. Devin Graham, who goes by the name Devin Supertramp on his YouTube channel, is a filmmaker from Utah, and he films crazy videos like this all the time.
The zip-line is about 10,000 feet long. Once they reach about half way they let go and parachute down to the ground. Talk about one hell of a ride.
I might do this is you could ride it the whole way down, but know way would I parachute off.
