Im Aaron from Oklahoma City, Oklahoma. I am the only sound/lighting/av tech person in my high school. Luckly it is a small school and im not that overworked.
Not being overworked is good! You've found a great place to learn lots about tech even if you dont have anyone else to learn from / with at your high school. In high school I was in that same situation, being the only real tech guy, I did learn alot from this site and still do! Please feel free to post away, add your comments and ask questions (and dont be afraid to use the handy dandy search feature b/c there are alot of topics on alot of stuff that you should feel free to read and bring back to life if you have more questions!)
