Sao paulo, brazil has a scary *** ghetto.
I had to pull over in a particularly rough part of the ghetto to puke (one of worst hangovers ever) and in the bathroom (if you could call it that) they just had a bunch of ripped up cardboard that they used as toilet paper (poor ********) and thier houses were just tin sheds with dirt floors and the was graffitti everywhere.
Lots of shady lookin people that I wouldn't want to meet in thier hood at night, but then again maybe I just thoughy is was scary due to the poverty
Could be that it was a perfectly safe place but I have just been conditioned to think that poor = dangerous.
