The Mission spot
Not a Marina-ite? City tradition and process of elimination rules that you are then, by default, a Mission-ite. They stay on their turf (Marina, Cow Hollow, Presidio, Pac Heights), you stay in yours (basically everywhere else), and never the twain shall meet.
The thing about the Mission is that there is no singular Mission to address. Maybe you're living above Mission Chinese with three of your closest friends, surrounded by rich hipsters, getting rabbled at by your elderly neighbor who has rent controlled his way through the changing demographic tides.
