Anyone from New York? I have a question about hip hop, can u answer?

Look up Brownsville, and if you ever go to Brooklyn, do not go down there, you need to know somebody who knows that somebody to go down there, it isn't a picnic its a matter of life and death. Like Brazil, i hear its pretty rough there, you have many ghetto's no ? the Amazon would be crazy, instead of a concrete jungle, you have the real jungle. Is it true that there are still tribe's that have almost no or little contact with people in the cities etc....?
