Around 8pm the light was starting to fade. We were one pitch below Camp 5. Interestingly enough we heard lots of voices above us.

There was the French party. There was the Nose-in-2-days party and there was a Nose-in-hopefully-5-days party. There five of them in the last party and they had 3 or 4 huge haul sacks. There was one guy who must have been 275 pounds. He was the designated haul bag mule.
