This is the 15 + or - a few feet high end of the COR where people tend to bottle neck as they take turn down climbing. IF YOU LOOK VERY VERY closely you can see a girl standing about 5 feet off the ground starting the ascent back up to the COR.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
