The lime green Mickey from home depot worked great when we were just there. I can't remember the other Dis'ers name, but it was ________ Tavern. We ran into each other on TT. He noticed my lime green Mickey on my fast pass holder and asked if I was on the Dis boards. He actually caught me off gaurd since he was the first one to ever approach me. It was great fun to be noticed by someone from the boards. I never did see anyone else, but I always keep my eyes open for the lime green.
*I do like the idea of a secret handshake though, lol
