Yes, San Francisco. Had a very nice day wandering around the city. I have to say the buses are efficient and logical, and make getting about really easy.
The downside was that when we got to the SF Museum of Modern Art - I have enjoyed it in 1999 - it was closed... Until 2016.
But then we walked the Castro district, which is the spiritual home of the gay movement, with Harvey Milk and shops called Hand Job (manicures etc. ) and Rock Hard (sex 'aids'). Next was Lincoln Park and the Legion of Honor (sp) gallery. Excellent Rodins and special exhibition of Impressionists on the Water.
On the way home I spotted a restaurant a block from our hotel called Baker & Banker, so we booked in and went later for an excellent meal.
