The Palace of Fine Arts in San Francisco, the site of the World Expo, presented by the Panamanian government in 1915, is an ancient Roman ruins building. It comes at sunset, sits on the opposite lawn and enjoys its reflection in the water, and watches swans swimming in the lake. Everything is perfect except San Francisco's freezing weather this morning and night. As a typical cool summer Mediterranean climate, San Francisco in September is said to be the warmest month! No wonder Mark Twain said it was the coldest winter I ever spent was a summer in San Francisco.
