Wow. Reading all this makes me realize how awesome my band program really is. I got to a school of more than 3,000 people with a marching band of about 300 (w/ guard.) Our band program has thousands upon thousands of dollars to share between the band and guard. Our girls keep moving up and up in the WGI circuit. Our school's only like 6 years old.
Back to the point: I think those shirt ideas sound pretty cool even though I'm not in the guard.
You are SO incredibly lucky!! There were only about 20 or so people in the band and my freshman year there were only three of us in colorguard. Haha. I think we had around 10 people in Winterguard are first year, but it was so much fun. I would have given anything to be in a big colorguard. Ah well.
