Whew! 15 minutes 25 seconds. The last 40 or so flights were so slippery from sweat and spit and whatever else that I almost bailed a few times. I probably could have come in under 15 minutes but there were a few groups I got stuck behind and couldn't pass for a while. I didn't want to bother asking them to move as they looked ready to keel over and die. Even so, I was pooped by the time I got up , and pretty much every person who climbed, myself included, was hacking up their lungs something fierce at the top!
