If you didn't know already, I work for the Student Activities Board at BYU. We plan free activities every week for students and last week's activity was the Halloween Spooktacular, a carnival for the children of students and faculty. It's definitely the most stressful activity we do, but always worth it.
All the kids on the stage after the "costume parade" for the costume judging.
