Fort Bragg and Redding are cold and foggy much of the time. Silicon Valley is in an ideal location. There are low-lying hills that keep the fog away, but it still gets enough ocean influence that it doesn't get too hot.

Fort Bragg is on the coast, and Redding is inland - they have wildly different climates. Redding is pretty damn hot, actually, and supposedly very sunny:

The politics are probably not something most SF people would like, though (nor I, really).

There are a ton of beautiful places around there, though, and in southern Oregon as well. The oak/madrone/pine forests in that area are extremely beautiful in my opinion.

Sorry, I somehow got Redding confused with Eureka.

Yes, Redding is uncomfortably hot.

In fact, that's generally true: everything inland is hot, and everything on the coast is cold. In between there's a narrow strip that is "just right". SV just happens to be in this sweet spot.
