What does your AD look like. Walking in to the stadium near your alumni tent, I was behind a lady dressed in a red dress suit and heels.
Assumed it was Julie so I gave a very understated "booooo". She turned around to see where it came from and I gave her a big smile and a friendly wave. She smiled back, took two steps, turned around again and said "was that a boo or moo?" She made me laugh out loud - well played! I smiled back and said "no, that's what OUR subway sounds like. ". She laughed and we parted ways.
Wonder if it was Julie???
Julie is a very tall redhead. if that is who you mooed at then it was Julie.
