It is true....for me. At my two schools(NC State, and NCAT) for anyone in the band, their day usually started around 6am, and didn't end till about 10pm. Between practice, classes, road games, community service, appearances and competition...it's alot harder to bag one of those chicks. They are either always way to busy or already in a relationship with someone they work close with.
But...every school is different. I'm just speaking from my experiences.
