MIT Mystery Hunt on This American Life

I just got around to listening to This American Life's episode about the MIT Mystery Hunt. This is the ultimate puzzle hunt challenge, probably the hardest in the country. Several NPL members make appearances—teams can include people from outside MIT, and as a result the Hunt is a mini NPL con. The TAL reporter tags along with a team on the Hunt. It starts at about 32:00, after a touching profile of an Irish unlikely quizmaster.
