re: San Francisco is dirtier than New Orleans.

The loser of this contest is determined by which one has the most bums, piss, and vomit in its streets. I've not been to SF enough recently to get a good measure, but in the past I would say NOLA was losing. SF had more bums, but they had a little class and original pitches. SF also had public toilets that kept a lot of piss out of the gutters.
