Donald Rumsfeld confused a lot of people when he rambled on about "known knowns," "known unknowns" and "unknown unknowns." But, flipping on the morning news and watching, in quick succession, a trio of stories featuring man-on-the-street interviews with Bay Area commuters explaining how they managed to survive 40 degree morning weather -- it all begins to make sense.
For Bay Area residents, the fact that it gets kinda cold in the winter is hovering somewhere between a "known unknown" or "unknown unknown." For any city dweller who has ever received the icy glare from a resident of the Midwest or East Coast when complaining about not-quite-freezing Novembers ("Yeah, you've got it tough there in the Bay Area!"), it's a known unknown. The weather's mild here. We know that. It's one of the reasons we choose to live here.
But the fact that cold -- real cold -- is ubiquitous elsewhere seems to be a total unknown for our microphone-wielding morning news reporters -- or at least their assignment editors.
