I've lived and worked in SF. Thankful that I'll probably never have another work-related reason to go back. SF is marked deprecated in my eyes.
Even with all of its problems, I will always love that city.
SF to me is just empty, cold, and only has big roads for cars.
It's hit or miss. I find large swaths of the Outer Sunset desolate and depressing. Places like this: https://goo.gl/maps/QQbarT8iGEqLfNuN6
