In this photo taken on Friday Feb. 10, 2012, a tourist takes photos of the Arena Fonte Nova stadium as it is renovated for the 2014 World Cup in Salvador, Brazil. The country's huge Carnival celebrations in February provided key lessons for World Cup organizers trying to prepare the nation for football's showcase event in two years. With tourists jamming many of the World Cup host cities, Carnival served as a test run for authorities seeking to evaluate their newly implemented World Cup projects, from infrastructure improvements to public safety programs to medical services.
