Brazil feels edgy. There is that mixture of great wealth and huge poverty. The very poor have no got a lot to lose. There is also the polarity between great architecture, the old and the new, and the slums of the favellas. There are the opulant churches which still hold a lot of the poor in their thrall. When life is hard and cheap I guess you have to believe in something. The Catholic church sure did a good job of brainwashing the poor.
The Olympic Games was coming. There was a mad building programme to remove a lot of the eyesores.
Then there is Nature. Even in the city a bit of the rainforest intrudes.
