For most of us who live in northern cali SF is not considered northern Cali. If you look on a map, that is a stretch it is in the central part of the state. And you do need to look at a map, hopefully a topo map. You forgot the entire sierra nevada mountain range and the southern cascades in your shortsighted view of the logging industry here. The area you omitted is larger than most other states.
The really sad part is that even though California has exported a sh!tload of liberals to other states (with terrible outcomes: Colorado, etc), it’s more blue than ever.
