Napa Valley grapes and vineyard

I lived in San Francisco for five years and while I was there I drove over to Napa Valley hundreds of times. It was such a great trip every time.  Usually it was with people who were visiting from out of town, but other times it was just to have fun. Napa Valley is such a beautiful area and it is one of the most popular tourist areas of the world. You can drive around and go from one winery to another for wine tasting.
