Did anybody else ever participate in this? It's held every year in the Columbia Tower in Seattle. 69 floors on SCBA. I did it yesterday for the first time. Didn't have a good day though. I've been fighting alergies for over a week. Plus something I ate didn't like me. After 4 and a half hours of waiting I finally got to go. Pretty much knew I was in trouble from the beginning. But I made it in right at about 30 minutes. Anyone else?
