Fans of the Colombian and Ghanaian national soccer teams held dueling rallies in Kansas City on Thursday to celebrate their teams' advancement to the next stage of the World Cup and to prepare for Friday night's match between the two at Arrowhead Stadium. Thousands of people clad in bright yellow flooded Mill Creek Park in a "banderazo," or large rally, to represent Colombia before migrating to the Marriott Country Club Plaza, where the team is staying, to celebrate the athletes.
