I was thinking, with 12,000 runners what are the odds of even seeing you on the course. Be thinking of a crazy outfit to wear. Otherwise, we will just look for the guy that heckles us the most.
Rick, I am the costume maker as well. In fact, I am thinking of starting a business making costumes especially made for runners -since costumes are so common in races/obstacle courses, etc. It's the second funnest thing about races -next to the beer, of course.
