If you visit Northern California, try to include a trip to the Marin headlands, and West Marin, and the Point Reyes area in your visit.
It will certainly be a beautiful and worthwhile visit, and will give you an idea of why many Azorean immigrants settled there, and worked on dairy farms.
The climate and landscape, and proximity to the sea is very like the Azorean Islands. I think the immigrants who came must have had tugs on their hearts, seeing such a familiar landscape.
There are Visitor Centers at the Headlands, hiking trails, and you can drive to some beaches. And as you are there, maybe on a lonely, foggy trail, think of Maria (from my book Maria and the Lost Calf), and how she loved living there on their dairy farm.
