Seems there are bigger things afloat at the Expo than just stamping passports and enduring long lines. City Weekend has uncovered an old pastime that has taken the Expo by storm: PIN TRADING. Everyone from pavilion staff to Expo volunteers are collecting, swapping and angling their way to get their hands on every nation’s pin. The prized pins are Canada and South Africa, but don’t take our word for it. See if you can get your hands on some and enter the foray of Expo pin trading yourself. If all of this sounds too intimidating there is always the Expo pub crawl. Instead of donning shiny metal pins you’ll be wearing Belgian beer stains and mojito mints to commemorate your Expo experience.
