With Rio being chosen as the site for the 2016 Summer Olympic Games, preparations are already under way for the equestrian competition. What is especially nice is that Brazil hosted the PanAm Games in 2007, so they already have the facilities built and in-use. The only major thing they need to do is add some more stabling.
An especially interesting note: the summer games will take place there during Rio's winter since it is in the southern hemisphere! It should be lovely for equine and human athletes alike since average high temps are expected to be in the mid-70s.
Here is a link to the Rio bid video. I'm pretty sure the promise of a private beach swayed a lot of votes. ;)
