The Gold Bar Rim Cliff in Moab Utah is 400 feet from the dry scrub flatland below and not even the kind of place to safely take a pleasant morning stroll, much less race along the edge. Don't tell that to pro mountain bikers and all-around daredevils Nate Hills or Kyle Mears, though.
Near the end of April the pair decided to take a leisurely ride at cliff's edge, one of the bikers strapped with a hi-def video camera. The end-result is 2 minutes and 44 seconds of pure white-knuckled motion-stabilized footage. Take a deep breath and enjoy.
Then take your bike for a sedate roll through the local park and don't even think about going near any cliffs in your own neighborhood.
