A few weeks ago, my daughter came home with a list of topics and an assignment to do some sort of project about something related to San Francisco history. She had been instructed to pick one that her parents knew about so she could get help with it. I scanned the list of possible subjects and spotted The Gay Rights Movement. That was a no-brainer. I grew up in San Francisco and remember the assassination of Harvey Milk as if it were yesterday. I spent a lot of time — for a straight kid with straight parents — in the Castro because it was close to where I had rehearsals and not too far from the Opera House. It was a neat place to hang out on the way home. So, it seemed obvious which topic would be best. After all, what do I know about cable cars?
