Look, it's Yosemite! I climbed Half-Dome! I'm terrified of heights, but after making it all the way to the sheer rock face, it felt stupid to not go the last 400 yards. In case you didn't know, that face is 45 degree angle with two steel cables bolted into the rock face. It's stop and go all the way up. I made it 20 feet before starting to sob hysterically. Strangely, the guy climbing up behind me was a psychiatrist and his teenage son was a sweetheart who gave me a hug when I got to the top. I then proceeded to pace neurotically until my hiking partners wanted to climb back down. STILL TERRIFYING!
