On the first night, when we were camped by the glacier and it was freezing coldout, I got the brilliant idea that it would be funny to strip down to our boxer shorts and make a raid on our neighboring camp. We snuck over after dinner, turned on our headlights and started jumping around and making strange noises. Just as people started to pop their heads out of their tents, we vanished mysteriously into the night. Like I said, it seemed like a good idea at the time and was a lot of fun. I blame the lapse of judgement on the altitude.
