Everyone speaks language of Olympic pin trading
If sports has cheerleaders, the Olympics has pin traders -- and they are serious about what they do.
Everywhere around Olympic Park, die-hard pin traders approach each other asking to trade pins.
Fans may not speak the same language, but everyone can say the word "pin." They want to trade pins from past games, sponsors, countries, religion, food, drink and even political persuasion.
Regardless of what they are, pins are how Olympic visitors connect.
"It opens the door to conversation to people I wouldn't otherwise meet. It opens the door to activities I wouldn't ordinarily do. I'm a school teacher. Here I am being interviewed on television. That would never happen but for pins," said Daniel Presburger, a pin trader.
One of the hottest pins -- and most controversial -- features a cartoon of President Trump and Kim Jong Un pitted against each other.
