I like it when foreign (to us) nations host the games, since I enjoy their opening ceremonies. I think Rio would pull off an impressive/colorful show to include their Carnival themes. Not sure if it would beat the presentation done by China, but I'm sure it would be close.
I would love to see Rio get it too.
I would love to see some of those Rio girls!
