spirit week?

Back in Student Council during my Gilbert High School days we would come up with themes the week of a big event and students would dress up each day to show their school spirit. I think during homecoming week we once even had a "Great Depression Day". Seriously. Does anyone else remember that?? Somehow 7 years later this has creeped up on me again. I coach tumbling a couple nights a week and our boss decided it would be fun for us to dress up the week of Halloween. Although she kept it on a lighter note than my previous spirit week experiences, the trick was finding a costume that went with the theme and that I could safely work in.
