I lived in Providence for 2 years on Federal Hill, which had it's moments with O.C., but South Providence and North Providence are no joke. Buddy cleaned up down town which when I was a kid you couldn't drive down there with out running over 2 drug dealers and 4 prostitutes, but he completely ignored the other parts of the city. Also fox Point is a junkie haven right near Brown University. Anyway for a quick read on Buddy.....
