Come to San Francisco for the second time. The Golden Gate Bridge, the Palace of Art, the Pan-American Pyramid, the Observatory, the Fisherman's Wharf and Stanford in my memory have become blurred, but the impression is that you know there will be such a bridge, a tower, a school there, which has not changed in all these years. This time, from bus to self-driving, the city became lively. It was just lucky to have a rainy day in California. My friend said it seemed to be San Francisco's first rain in eight months.
