Beautiful picture and plane. The SF-Oakland Bay Bridge is obvious, with Yerba Buena/Treasure Island right below. But is that red tower on the north shore to the left the start of the building of the Golden Gate bridge, or is it out of frame? The bridge was started in 1931 and completed in 1937, and the Boeing 314 was built in 1936. I think the former. Cool.
Either way, beautiful shot, beautiful plane, beautiful city.
