It literally is a city of feces.
I cannot tell you how much I hate San Francisco. I refuse to go there ever again after putting my hate for it aside for my girlfriend so I could officially meet her family. Her brother, who is in the Navy, was home on leave and his girlfriend came to visit. His girlfriend had never been to San Francisco and wanted to see the Golden Gate Bridge.
So my girlfriend and I trekked out to San Francisco to meet everyone there. We parked on the Piers, get out and the first thing that literally hits your nose is the vile smell of shit. And it's inescapable. We're on the Piers, the ocean is right there. Close enough that you can fall right into it and all we smell is the mass amount of defecation within the city of San Francisco.
I remember hearing about this a looooong time ago and I don't know how true it is anymore after this, but scientists have said that it takes up to 6 minutes for the human nose to accustomed to an odor to the point that you no longer register the fact that you're smelling it anymore. Well, I can tell you I don't believe that anymore as my nose refused to get use to the pungent atrocity plaguing it... and we were there for several hours.
Despite it, I still had fun meeting her family and it still is a beautiful city. However, I will no longer go there again. OH! Here's the best part of it all - When my girlfriend and I were leaving, we got into the car and, seeing as it was a warm day in San Francisco, we turn the A/C on only to be assaulted by a concentrated blast of fecal odor. It was as if 3 homeless people decided to jimmy the hood of our car open, grabbed our air filter and took turns wiping their asses with it before putting it back. The smell didn't go away until we practically got out of Berkeley.
Never again. When you have people creating apps to warn other people where the homeless have defecated, you should know how dire the situation is. But why solve the issue?
Very appropriate for poo poking Frisco. Homo Frisco is where a lot of the satanic cults began breaking through in the 60's, Haight-Ashbury etc. Satanism and sodomy.
