I have no understanding of street smarts, have never been outside my own country, and speak no Portuguese. Am I in for a bad time visiting Brazil (Porto Alegre, Florianopolis, Sao Paulo)? I plan on staying within the touristy areas, not get drunk or do drugs, not fuck around, and stay out to a reasonable time. There's not really a good reason for that to be considered unsafe is there? Or is there?
