Let's also not forget the animal element of street poop here. I live in Russian Hill, a not rough part of SF, and I daily see people neglecting to clean up after their dogs. These people belong to no particular group: young, old, rich, poor, students, tourists, your neighbors. There's something about this city that attracts people who just don't give a damn. It's unsustainable for those of us who do. Also, homeless people tend to poop in between parked cars on the street or in doorways. If you see a fresh turd in the middle of the sidewalk, I'd say better than 75% chance it came from Fido, not Frank. EDIT, I might live in Russian Hill but I walk through the Tenderloin every work day for my commute. I see it all.
