While not a wine lover, am going to suggest skipping Napa proper, go a little further north, rent a bicycle, and follow the red line (or better, use it as a rough guide and find more on your own). Easy to do in an afternoon. Could see more the next day without much effort.What's the sitch in Napa nowadays? We like the touristy tours and tastings. Not enough of a connoisseur to spend bucks on private tastings. Any recommendations?
