Frisco and Leander have very similar demographics. Tech heavy upper middle class. In other words, lots of "nerds" that played in band when they were in school that have money, time and resources to help and support. Lots of stay at home or work from home parents.
The interesting about CP is that won a few state championships in football and other sports also, but somehow band is still what the cool kids do. Choosing between football/sports or band is a real dilemma for incoming freshman.
