If we are being honest, wineries are opening up like crazy all over Cali. Morgan Hill, which is a small city below San Jose is becoming really popular for their wineries. If you want smaller wineries but with tremendous views, Santa Cruz and Monterey have some great spots. If you don't care so much about scenery, but love gigantic wineries with fantastic wine, Paso Robles is a very popular spot.
I crap on Cali a lot (deservedly so), but don't get me wrong. When you can get out of San Fran and LA and find places to avoid the traffic, the state is pretty damn amazing. Monday went to the beach with my girlfriend, unbelievably soft sand and a completely empty beach for a half a mile in each direction, talk about a very relaxing way to spend a day.
