Jeremy,
I am one of the 3 guys from Seattle that was on Serpentine that day with you and Salz. The guy who was rapping was one of ours. He only had tennis shoes for the hike down and he was picking his way down on the earthy terrain. We weren't on the "main" trail for most the way. He got cliffed out and decided to just rappell instead of walking around.
I saw this forum title and laughed.
