I like Saunders, but as a resident of SF and daily passerby of some of the parts she mentions, I haven’t noticed much if any difference vs previous years. And I have lived here 30 years now.
My son lives in SF and I’ve been there to visit several times in the last few years, most recently in May. The city may smell roughly the same as before to you, but to someone who is not entrenched in the sewer, the smells of San Fran are horrendous. I suggest you give your nasal passages a change of venue.
