As a teacher, sometimes your gut tells you to do something and it turns out to be a really good idea.

That's what happened in October, 1994. I decided to dress up as Groo the Wanderer for Halloween. I never dressed in costume for school before and back then, no many did. A few students and very few teachers.

Over each of the next 20 Halloweens, I did something different. Sometimes solo, sometimes as a pair and more recently as part of a team.
