First off, let me qualify these statements I'm about to make by saying I was in a marching band for 5 years and I work with a high school drumline now...(not that you guys needed to know that)
I believe mainly that 1. It's hard to get back into the power T because during pregame before the football team comes onto the field, the pride marches down into a couple of straight, squished together lines..then they come back out into the T...
This way, the football team comes out of the tunnel, and turns left..
2. There were recently some NCAA rules that stated that a marching band couldnt take up a certain amount of the field or something like that..Im not sure... but whatever this rule is, it may have something to do with it
Hope this makes a little sense....its mostly speculation.
Im tired so this may not make as much sense tomorrow when I read it again......g'night!
