I had visited San Francisco about 5 years ago, it was a wonderful place and still is.
But two things:
The nicer areas seem to have gotten nicer
The not so nice areas seem to have gotten worse
Fisherman’s Wharf is like Disney world less Disney. The Bridge is nice but it is just a bridge. Alcatraz and its history is cool. But beyond that? What is there? I mean, it is a wonderful place to live if you can afford it I’m sure. But, I don’t get why some one would visit it as a tourist.
But that’s just me.
