BONKERS TOWN I have made it known that I'm basically a coward. The most daring thing I've ever done is look down the barrel of obesity and eventual heart disease. And that wasn't even on purpose, I just really like potato chips.

This video is a cold dose of reality that I am not an adventurous person and have no desire to become one.

Climber David Calhoun was climbing in Red Rocks Canyon in Las Vegas when he saw someone coming up behind him, fast. The climber quickly caught up to him and Calhoun soon realized this guy had no ropes connected to him and was free-climbing the whole way.

Watching the video my heart started racing and I started yelling at my screen in hopes this climber would hear. He did not, but he made it up and seemed just fine.

While this is insanely impressive, it's also insane. We highly suggest that if you go climbing to take a page out of Calhoun's book and do it safely.
