And please don't be surprised if you don't see any orange Chargers with the Confederate flag on the roof or any white Cadillac convertibles with bull's horns mounted to hood/bumper.
One last recommendation. When visiting a winery in Napa/Sonoma or anywhere on the CA coast, please don't use spittoon on wine bar for spitting your chewing tabacco or the wine. It's reserved for pouring the excess wine in your glass that you don't want to drink.
