Weather should factor into the experience of living somewhere. From what I have heard (I've never been), San Francisco has a great climate. What I don't like about KY is the weather, this past summer it was over 100 several days and just plain miserable. I remember the summer before that was really bad, but not as ridiculous as this year. Granted, last winter was incredibly mild. Some winters are just to the point of unreal, like an ice storm that pretty much disabled us for 3 weeks.
