Right the 5% I mentioned which tells me you’ve never been to any of the 95% in either of those 2 cities.
Pacific Heights, The Marina, Cow Hollow, Russian Hill, Nob Hill, Presidido Heights, Hayes Valley, Noe Valley in SF to name a few amazing areas.
Queen Anne, Magnolia, Ballard,Fremont, Wallingford, Madison Park, Lechi, to name a few in Seattle.
I’m not denying the bad areas are bad same as any city, but at least you won’t get murdered.
I’ll be in SF this weekend and won’t see or smell anything you talk about and will probably walk 20 miles through all of the neighborhoods I list.
