Things I have learned in the last 15 years traveling with church bands and youth bands, oh yeah and the whole colledge thing....those little short specialty power cords for your amps/keyboard etc., have a tendancy to get seperated form the things they power,and you cant replace them with anything else, so make sure they are there before you leave, and always pack an extra. Take a drum key, guitar strap, and xtra picks, sustain pedal, etc.. you may not be a musician but for some reason they expect you to have these things, and if you save their butt once or twice it gains you respect real fast. I started when I was about you age, so I know all about being looked at as just a "kid" when you know way more than the adults but they just won't listen. Leave yourself lots of extra time to set up and test everything, and let it run at volume for a bit to make sure you don't have power or overload problems. If you think you might need it grab it, you may have to carry back in some extra stuff, but it's better than kicking yourself for not picking up that whaterv it was you left in the storage room. Trust me. Good luck, and may God bless your efforts.
