As Michael Phelps prepares to go for gold medal #146 in another nail-biter at the Water Cube and Bela Karolyi comes down from the blood pressure spikes induced by last night's all-around competition in women's gymnastics, we bring you today's Friday photo to shed light on a type of Olympic spectator who is on pins and needles about, well, pins. John Schmidt (pictured above) came to Beijing from his home in Kentucky prepared to trade, sporting the vintage enamel-studded khaki vest that is the mark of a true collector. And apparently, these games have not disappointed. "Trading has been great," veteran pin trader Dan Baker told CNN of his experience at his thirteenth Olympics. "Everybody who is anybody is here and they all seem to have pins. And they are all beautiful pins."
