Yes. You can stroll about nude in broad daylight in certain districts of San Francisco. Most restaurants discourage that kind of customer, for obvious reasons, unless they bring a pillow to sit on. When it happens’ it’s almost never anybody you would want to see w/o clothes.
I’ve heard that many parts of San Francisco have the unmistakable miserable stench of urine in the air.
SF has tried to be very lenient and liberal with homeless, nudists, extremists in the LGBT community, etc. But where does being liberal get you???? You end up pushing the envelope too far, and then decent people avoid your city.
