Videos have been posted about this place (Kensington Ave, Philadelphia) for years. I'm not sure which is more disturbing, the poor bastards that live there or the creeps that film/watch them.
On a lighter note, there does seem to be a vibrant community, with very little racial or social tension. I'd imagine you would be just as likely to get stabbed whatever your colour, creed or pronoun. It's a step on the path to a multi-cultural utopia.
