I marched with Bayou City Blues (Sr.) from 94-99 (which would have been my age-out year). I auditioned for the Cavaliers in 95, but couldn't march due to financial reasons. I would have enjoyed it, I'm sure, but I do not regret doing DCA instead.
I loved it so much that when I had an opportunity to march again, I competed with the Gulf Coast Sound from Houston in 2006-2009.
You can't go wrong marching in DCA if you have a passion for the activity. Hope you enjoy your experience as much as I did!
