I won’t (now) get into the cost overruns and delays plaguing the Rio Olympic Games, which will take place almost a year from now (August 6-20). Nor will I go into the short- and long-term value to Brazilians of staging their second mega-sporting event (World Cup in 2014).
Here is a recently released video showing current progress and future vision of Parque Olímpico in Jacarepaguá, the western part of Rio de Janero, your host for the 2016 Summer Games.
