Hi Mom Alicia,
Being entirely objective (and nothing against Chicago) it was a honest and great choice. The Olympic games should take place eaqch time in another place, equally spread on the universe. The USA is sure NOT discreminated (just count how many times it took place there). Personally I am thrilled and seriousely think to take the advantage and visit Brasil at that time and the highlights (for me) will be watching the Olympic games.
Best regards,
