UPDATE FROM RIO
Today we rented bikes and rode around the big lagoon in the city. We ate lunch at the House of Switzerland, which is a restaurant/bar set up next to the lagoon by the Swiss for reasons that are not immediately apparent. It's a nice place to have a beer.
They have large fiberglass cows there. Swiss Pride, baby.
There was also a band playing traditional Swiss samba music.
From there we went to the beach, where we drank coconut water from actual recently slain coconuts. Everybody does this here. I frankly prefer the beer.
