But aside from him, I can see how most directors here justify their advocacy of marching band. Football is so big in Texas that marching band is the most popular form of band in the eyes of the public, which makes marching competitions the most important competitions in the eyes of the administration because it is the biggest in the eyes of the community. That in itself means that if the bands want to keep the support of the people that are supplying their budget, they have to do whatever they can to do good in marching band, no matter the cost, which is why they won't let good players opt out of it.
And from the students' perspectives, at least in my school, there was a lot more interest in marching band than in concert band. Most people would nearly completely lose interest after marching season ended. It's not like every student goes on to become a music major and most don't do any playing at all after high school. There were only maybe one or two each year from my school. I always just made sure that I kept myself in check when I would get tired and such. Needless to say, I didn't have a good relationship with my head director, but it was my last year, so it's all good now XD
