In this May 26, 2013 photo, the field sits empty inside the Mane Garrincha national stadium before the inaugural soccer match between Santos and Flamengo in Brasilia, Brazil. For decades, Brazilians simply raced into the stadiums and grabbed the best spots, some sitting, others standing in a crush amid thousands of others. Traditional general admission is being eliminated with luxury boxes and modern seating taking over at the six stadiums being used for the Confederations Cup, and the additional six that are to be ready for the World Cup.
