If you do afterparties, don't make the mistake of taking google's advice on which buses to take to get to the Empty Bottle from the festival grounds. It requires a transfer in one of the less safe parts of Chicago and buses don't run there frequently. Not only did I miss Nachtmystium, I was also gawked at by unaccompanied children who walked up to me and said, "I love seeing white people here at night!" then ran off laughing.
