From Sacramento

Take I-80 West toward San Francisco. Once you reach the Cordelia area,
exit onto Highway 12 going WEST. Turn RIGHT at the second stoplight and continue
traveling on Highway 12. Keep to the LEFT where Hwy. 12 merges with Hwy. 29
toward Napa/Sonoma. Continue along and turn LEFT at the exit for Highway 121/12
toward Sonoma. As you approach the second light bear RIGHT onto Napa Road
(Nicholson Ranch Winery will be on your right.  If you pass the Clover Stornetta Dairy
you have gone too far.)  Continue until the light for Broadway (you will see Friedman's
Hardware store and a store called the Salsa Trading Company on your right). 
Make a RIGHT onto Broadway.  Continue until the road comes to a "T" at
Sonoma City Hall.  Make a LEFT onto West Napa Street.  Take this about a mile. 
You will see the El Pueblo Hotel on your you right, bear to the right just before the
light and the Trojan Horse Inn is immediately across the street to your left.
