As a volunteer at EAA for 47 years straight, I thank You for the recognition. It's an honor to be able to do these things for the good of all EAA. I've done everything from picking up field stone in 1970 to... well... I don't know just what I like doing best. Anyway, Thanks!
As for the yodeler, I believe he actually flew west a few years back, so yodeling is his two and a half minute volunteer contribution every morning till we lose the sound bite.
Happy Landings!
