golden gate bridge
Recently we took one of the tourist cruises during sunset on the bay. The premise was not too thrilling, and knowing that it was a touristy activity, the expectations were not very high. However, we were pleasantly surprised by the outcome, and enjoyed it very much.
Looking at the Golden Gate Bridge, we were amazed at home such a structure exists. The history is that it took so long to find the bay because the fog would not lift. And to think that workers were there day and night inserting steel into freezing waters, at times unable to see further than a few feet in front of them. What a feat!
