As I was saying, there is a little something for everyone in the great city of San Francisco and just because something appeals to a much younger crowd, in no way indicates that it can't appeal just as well to an older or young again crowd. I remember some of the things that fascinated me most as a child still spark those feelings of happiness and joy (we won't say how many) years later. The important thing is to choose the activities that appeal most to you and try to enjoy yourself as much as possible. It shouldn't be too hard!
