I lived in Crawfordsville until we moved to the east coast in the early 60s. My dad used to take us to the Indy 500 Time Trials. This is when they looked like soap box derby cars. I don't know if he ever went to the races...I was pretty young.
I played Constitution Hall when in high school band. A couple of graduation ceremonies took place there. It was pretty cool to be in the back where the musicians would get ready & warm up.
I also played in the original Feline Fine Arts Center at Wolftrap Farm Park (before it burned down) for another graduation ceremony.
I assume you were in high school/college when you played at Indy? Did you see Jim Nabors sing?
I recall when I stepped into the role of "the old guy" at work through the eyes of younger employees. They always thought I was lying when I told them people used to smoke at their desks. Jeez, folks, it's not like I said I rode a horse to work!
