The Napa valley is not so far away from our hotel. It's 90 min to drive with our car, a huge Ford, that seems to fall apart when I close the door. It was getting warmer and warmer the closer we came to Napa. Napa is also a village. I could see there where the grapes of my favourite wines grow.
The Napa valley is surely a wealthy part of the US. Wineries are everywhere. Classy restaurants are along the streets.
