I've been trying to think about what I put...and I agree that they just want to learn more about you, and look at what makes you stand out. I remember at an Open House for SUNY...that the guy giving my tour played Ultimate Frisbee..and the school loved that he was a hard working student, yet he managed to start a ultimate team at his school. I kinda used that for direction. I think trying to be honest, yet original/unique is always in your favor. Good Luck!
