@Fil Albuquerque,
It's more interesting to hear personal observations of popular places visited.
There are plenty of non-personal photos of world famous sites.
The Golden Gate Bridge is one of the world's most famous sites. It's almost 9000 feet long and 90 feet wide, and was built during the 1930s. The span between the towers made it the longest at the time. It was an engineering feat because when they placed the middle section in place, they had to consider the expansion and shrinkage of it.
There was also information on how much the bridge can swing in high winds.
