If you have ever driven up or down Napa Valley, then you have seen the sign. With prominent placement in the movie Bottle Shock, this wine is a landmark of America's finest wine country. As a person who loves to get a shot of these types of landmarks (think Hollywood sign) I just had to make a quick stop with my girlfriend, especially because we had caught a great sunny day. Make sure you get the panoramic mode working on your iPhone so you can capture the beautiful mountains and vines in the background.
Then get out and taste what the valley has to offer!
