I remember driving through SF about ten or so years ago. Yes, the Church of Satan was in plain view, not far from the public library where I did some research. It looked like all the homeless schizophrenics lived on the sidewalk outside the library. While I was there my wife and daughter did some sightseeing in the car I rented. They told me how they passed a large billboard of some naked gay men, then passed a park where gay men had sex out in the open. Just the sort of thing you want your wife and daughter seeing.
