I live in Bernal Heights. Maybe that's why I haven't seen a human poop on the sidewalk in.... well never, anywhere near me. Probably seen it twice in 20 some years living here, and not anywhere close to here.

Were you aware that the Tenderloin is, ya know, what it is, before you got an apartment there? It's been well known as the seediest part of the city for a century or more.
