It looks a little insane, but for those that enjoy the adrenaline rush, the Red Bull Cliff Diving World Series offers plenty of thrills.  Below is video of the latest event at Possum Kingdom Lake on May 30.  Competitors from around the globe take part in a series of dive challenges to see who is the worlds best diver.  The platform at Hells Gate at Possum Kingdom is 88 feet above the waters surface, more than the height of an eight story building!
