You know, some of us like weather that changes a lot more, also killing frosts/freezes kill a lot of nasty bugs (although I'm not aware of the Bay Area being know for that sort of problem, maybe too dry?). A quick check indicates you can go decades without a white Christmas, and Wikipedia says about San Jose that "On average, there are 2.7 nights annually where the temperature lowers to or below the freezing mark".

I could rebut with the single word earthquakes, was even in Silicon Valley when the 1983 Coalinga earthquake (https://en.wikipedia.org/wiki/1983_Coalinga_earthquake) hit.

Then again, I was also retired to my home town of Joplin when the 2011 tornado hit (http://www.ancell-ent.com/1715_Rex_Ave_127B_Joplin/images/), but one convenient thing about tornadoes is that you only have to walk a few blocks perpendicular to their line of movement to get to undisturbed buildings and such, the aftermath is therefore a lot easier than wide area disasters like earthquakes and hurricanes.

Many people like that, but just as many if not more don't.

Slipping on the icy stairs in Chicago where I grew up and lived most of my life, before walking to the train and having my glasses frost over from my breath did it for me. Then there are the insane humid summers.

Being able to go outside practically whenever I want and not feeling guilty if I stay indoors was worth moving to the Bay for me. We also have gorgeous long falls here where the leaves change color and everything.

Don't underestimate how many people loathe crappy weather.

I don't disagree, hence my use of the word "some", and I think Chicago's combination of very cold winters plus humid summers would not be to my taste. Experience shows I can tolerate one or the other based on living in the Boston area for a dozen years, and the rest in the Joplin and D.C. areas which are pretty similar, on the order of 15 degrees F higher in the day during the winter than Chicago.
