I disagree about Glen Rose. They used to have UIL Marching Contest there before the Region split and schools were assigned to other regions. The warm up areas, travel, stadium and track worked for us. We had no bands passing through us as we warmed up. If you were referring to bands passing by, that's correct. They passed by to get to whatever area. They didn't march by or use cadence. They just passed by, but not through our band. I don't see how this is a problem.
