I thought NYC was the dirtiest place I've ever seen, sounds like there's competition!
Neither are as dirty as New Orleans. There's trash, there's excrement, then there is rotting catfish and shellfish on top of the trash and excrement and it just sits stewing in stagnant, humid, swampy and hot air.
I live in the Lower Ninth Ward and based on what I saw of SF last fall I’d still give that award to SF (unless comparing the few weeks after Ida)
I was actually going to go there last year for a show, until nature decided to try and destroy it again (though I hear the hurricane wasn’t too bad)
The few weeks afterwards when the trash wasn’t getting picked up made me hightail it to Mobile for the duration.
