I was never in the band, but I absolutely love the marching band sound. The thing about Allen's band, its not only big, it's very good. When you have that many instruments working together at the same time, it makes for a beautiful sound.
McKinney Boyd also has an impressive band. They actually work a light show into their show, the lights are in sync with the music.
Yeah, four of my kids graduated from Lewisville High. Each of those classes had 1500 grads in it. It takes a long while to get to the "Ls"
