Now, the whole place seems like the Haight in the 60s.
You never know where you'll see oddly dressed and undressed people roaming the streets.
Remember when public nudity was frowned upon? Well, in SF - it's just another day. They protest nude (http://www.nakedprotesters.com/), run nude (http://www.baretobreakers.com/) and parade nude (gay pride - barf - parade).
A few months ago, my daughter was visiting, so we decided to drive to Point Reyes to sightsee. Going through a Marin County college town, we stopped to let pedestrian traffic cross, including one young woman wearing her bra outside of her dress. We never did figure out the point, but we did find it amusing.
