I remember that on my 18th birthday, I managed to be picked as a extra in Indiana Jones. I didn't look 18, so when I was on stage the casting director asked me if I was 18. I told her it was my 18th birthday and a lot of people wished me Happy Birthday. It was fun, and the first teme I tried to be an extra as someone who was old enough to be. I'd definately get the buttons noe that I know about them, and the scavenger hunt sounds fun. You have to post a report after you get back.
