A fair number of hikers do this hike at night. Unfortunately, many of them are loud and celebretory when they get to the top, even when they see that everyone up there is asleep in their bags very late at night or in the wee hours of the morning. My favorite was when the three of us who were up there were asleep in our bags on a pretty cold night. I wear ear plugs up there, but I could hear someone calling out, "Hello? Hello? Hello! Helllllloooooo????" He didn't sound like he was distressed, but just in case he was, I responded. As soon as I did, he yelled, "Awesome. Can someone take my picture?" Call me grumpy, sleepy and freezing, but I did not oblige.
