My first experience at Comicon was incredible! I went as Sally Jupiter from Watchmen with my friends as Protoman, Ramona Flowers and Scott Pilgrim. At least one of us was asked to stop for photographs at least every other minute, Protoman and I were pulled aside for an interview with a Japanese news show covering the convention, and we had an chance to see a live demo of Assassins Creed III. So much fun!

I am a high school teacher and two of my students went there. They had a blast and I was so proud of them to follow their dream.
