Golden Gate, San Francisco (I've seen this and drove on it, but I would love to do it all over again!) Fort Point is a very cool attraction to check out. It is located under the GG bridge on the south end.
Golden Gate Bridge, San Francisco/Oakland, CA. My dad sailed home from WWII after 4 years in the So. Pacific & said that the Golden Gate Bridge again was one of the most beautiful things he'd ever seen.
