I haven’t seen much poop (although sometimes neighbors throw bags of dog poop in my garbage can, grrr). Seattle attracts more homeless per capita than SF, although the problem is obviously not as bad in the winter as it is in the summer.
I live in San Diego and every morning at around 6 AM downtown There are people pressure washing the streets. I like to go for early morning runs before work and if I go any earlier than 6 AM it’s a mine Feild.
