I marched one parade in HS (I was a violinist trying to learn french horn - miserable failure!). They pinned me between 2 other real horn players so I couldn't mess up too badly. I basically just carried the horn. I am convinced that the first person to ever suggest a marching band did not play an instrument. In college, I spent one year doing flags for the band director/friend. We were such a small school and he needed one more person. Violin teacher was furious but, what can I say? It was fun. The football team was abysmal so the band WAS the best part of the game. I nearly took out a football player who came on the field before we were done practicing. And, I got belted with the end of a flag more than once. Fun times though. Do love a good football game...
