SF has a purpose, to attract all the wingnuts to one place, kind of like a Roach Motel for freaks.
My apologies in advance to any freeper who lives there because it's their hometown or they work there.

“...kind of like a Roach Motel for freaks.”
Austin serves that purpose in Texas....but now, there are so many freaks that crime is getting to be a serious problem. There is a vicious rape reported on the TV news about every other day now. The merry band of cops on bikes isn’t getting the job done any more.
