Chicago: Get over yourselves. America, too. The United States has hosted 8 Olympic games - Brazil? Nada. South America? Zilch.
August happens to be winter for Brazil and Rio de Janeiro has a similar seasonal pattern as California - a wet season and a dry season. We like to keep it real simple, us Californians and Rio de Janeiroeons. Although it sounds like their winters are like 70-80 F. Nice!
Plus: Chicago view v. Rio de Janeiro view <--- Yes, please!
