I had what I thought was minor knee injury prior to move-ins in 06. About 2/3rds of the way through the season, rehearsing for the Denton show, my knee hyperextended, and I tore my ACL and meniscus cartilage. Had to go home and get surgery, then I was on crutches for a month or two.
07, during a show in Arkansas, I over-hyped a visual and re-tore the cartilage. I couldn't march, but I stayed on as a conductor and ran the met.
