I believe there have actually been 16 deaths on the cooper spur route, If I'm not mistaken, it's the most deadly route on the mountain. Many people think it's just a step up in difficulty from the south route. It's a BIG step up from the hogs back route!
"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."
