My brother plays rack in the pit for Revo. They definitely have had several guard members join late. They wouldn't let them march in the exhibition show in San Antonio 'cause they didn't know the show well enough yet.
I get to go see them in July when they return to San Antonio for the DCI SW Championship. It'll be my first DCI show ever, and I get to see them, the Blue Devils, Cavs, Santa Clara, and oh man, I'm excited. I'm so proud of that kid.
