My son marched lead euphonium with the Oregon Crusaders between 2010 and 2014 . During that span of time, OC went from a not quite top-tier open class corps to open class world champion to world class marching a full 150. Not bad for a corps that formed in 1971, then reformed and folded several more times with long stretches of dormancy in between. In 2007, the first year of the latest iteration, you could count the brass members on one hand!
I say all this because it has been SO exciting to see this massive explosion in the organization. For the first time OC marched a full corps in 2014. Since then they've made semis comfortably every year and I know it is only a matter of time before they break into the top 15 and then finally that holy grail - finals.
I have volunteered at one time or another for the full scope of fundraisers, training camps, tour, and events associated with drum corps. Yes, I have done my time in the cook trailer!
These days, I am a drum corps superfan. I continue to learn more about the activity, its history and evolution, along with all the intricacies that make up a show and season. I am a retired music educator and can comment quite intelligently on the music side of things while still learning about what general effect and visual are all about.
