It's my pleasure sir! I've been feeling the same way for a long time: Why drum corps international have the international division though they call themselves "international". So...your topic is interesting to me!
As you just said above, I also think that it would be great if DCI become a truly international circuit...like the Olympic Games. It's already talked in this topic, but I think one of the big issues that makes it hard is age-out system. Since DCI is a youth activity, I think they need and should keep the system. However, I don't think any countries that have drum corps activity have the same system as DCI. Therefore, in order to bring international competitors to DCI, I think we need to make a new system/rule.
