FILE – In this July 28, 2012, file photo, fireworks illuminate the sky over the Olympic Stadium during Opening Ceremonies at the 2012 Summer Olympics in London. Always splashy affairs, the parade of athletes this time around will take place Friday night, Aug. 5, 2016, at Maracana Stadium with a country-by-country show of fashion, along with speeches, flag-raising and the lighting of the Olympic cauldron. The idea is to showcase the host country’s culture, something that has earned oohhs and aahhs through time, usually also accompanied by some head-scratching as traditions and history play out.
