Oh look, there are also "fanatics" in Olympics pin trading. How unusual! :)
I don't quite know when the Olympics started having pins (I'm sure it was way before Disney got into it big time). But I'm guessing that the quantity might now be as many and as frequent as Disney pins. :)
Speaking of which, it is barely 25 more days before the big Pin Celebration at Epcot. All we're doing now is waiting for our RSP to come through.
