Truckee, Grass Valley and Davis

The past two weeks I have been traveling the state exposing the world to Esterlina wines. I'm having a great time meeting new people and seeing new areas. In past travels I just drove through on the boring highways. Now I have the time to actually get to know an area, walk the streets and absorb the differences.
Truckee, for instance, is more than a spot on an interstate which needs to be resurfaced. It is a vibrant community with an historic feel. There are also some great wine bars and restaurants.
Grass Valley actually has a old town section with a variety of interesting shops and restaurants as does Auburn. So many of these towns have grown without preserving their character so it's rewarding to see areas which care about their history.
Davis is a college town with a nice leafly tree lined aspect. There are trails running for many miles next to the creek and arboretum. I even found a preserved redwood grove in the heart of town. I can see why many college graduates don't want to leave.
If anyone knows of some special places I can talk to about Esterlina please let me know.
