I have to point out what everyone else is thinking.. football and band camp? so many jokes... from, well, band camp..... to american pie..... to comparing band camp to football, and let's throw in a solid flute reference for good measure...
however, that is a good question and I'm curious of the answer as well.. I'm assuming there is quite a bit of down time where most guys are learning the playbook, as well as doing themselves a favor by asking coaches and players about technique, etc... I doubt there is much film to watch but it's possible.
Band is a serious thing! Got to stay in shape....there are muscles in use which have to be finely tuned. (My last marching band director in college even made us run laps...we had a pre-game show which involved running on the field. The entire band laugh at first when he told us to run...then when we realized he was serious there were some other comments.)
However....I knew you guys would have fun with that "comparison." I was laughing as I typed it imagining the responses. Hope most of you know I am smarter than that. You handled the reaction fairly delicately.
Still, does not look like a grueling schedule or much practice for something that is called a camp. I know things have changed with the new agreement.
