Unfortunately, I saw them create quite a stir by racing (dangerously) through a crowd. And I'm pretty sure they knew that they shouldn't be doing that, because I later ran into a group of 19 to 20ish men who were carrying around identical brown paper bags with handles, filled with black costumes... ie, they snuck themselves in, and changed inside to create their sensation.... they made themselves scarce when they saw me eyeing their bags....
