I'm from a small podunk town and had never really seen people at home wearing letters. I went home at Thanksgiving this year and saw a handful of people at the theater wearing letters.
Oh yea, when I was in Tennessee last summer I had some random lady come up to me and say she was an AOII too!
It's kind of cool to be across the country and have a sister walk up to you while you're in letters to say hi and everything.
