It was pretty quiet when we went back there around 1 PM or so on Sunday, July 22. There were 3 CMs handling the pin trading. They were standing near the entrance to the area underneath some large umbrellas. They had an interesting looking pin trading wheel with lots of pins and another big trading board. I guess there is also some sort of tic-tac-toe trading game for younger kids to play with the CMs, but we didn't investigate that. The CMs were very friendly; there were no lines. We didn't find anything to trade for that day though.
