The Olympic Games are about to begin in Rio de Janeiro, but what will happen once they're over?
The deserted Olympic venues in Athens might offer a clue.
Unlike the 1984 Sarajevo Olympic venues, which were destroyed during the Bosnian War, there was no catastrophic event that led to the abandonment of the Athens arenas.
Greece simply has no use for world-class, expensive-to-maintain venues for niche sports like softball, beach volleyball, or even swimming. They became useless immediately after the Olympics left town.
As a result, more than a decade after Greece spent about $15 billion to stage the games, some of these once gleaming venues are crumbling.
