Some more info: busking in Brazil is absolute heaven. You will make enough money to eat well, huge all-you-can-eat buffets, ice cream, cigarettes, even a few beers here and there.
Brazilians love anything that is different. Telling them you're American gets really positive responses. I play the harmonica, they have never really heard someone play the harmonica in person, and are very interested.
Brazis very relaxed about camping. You can camp just about anywhere and no-one cares. You don't even have to ask the security guard. And that same security guard woke me up with a cup of coffee about 50% of the time
In Uruguay now. It will be hard to top this short time in Brazil. Afterthat it's back to Brazil and I will keep posting here with information about northeastern Brazil and the Amazon.
