Man Walks Tightrope Over Yosemite With No Safety Gear

Call it dumb, lucky or maybe even incredibly skillful?  A 23 year old man was captured on video high lining across a steep gully at Yosemite National Park in California.  Basically this guy walked across a tight rope, over Yosemite with nothing to save him should he fall.   

Michael Kemeter (23), made four crossings total and eventually did one without safety gear on.  You can check out the footage for yourself below.  I'll stick to planking thank you very much!
