I didn't realize how big a deal pin trading was until this past weekend when we went to Disneyland (again). We walked through Downtown Disney and next to the pin store, there were these hard core folks with suitcases full of pins to trade! Man. There's even a pin trading etiquette guide I found online. I just buy pins that I really like. My friend Shirley found these really cute flip flop Minnie and Mickey pins for me (it was a pair), and Anthony found me my little green men pin this weekend. I was stoked! I just wear my pins on my lanyard that I have to hold my pass.
