Imagine you're driving along the Pacific Coast Highway heading south from San Francisco on a bright, sunny day. The hills are on your left, the ocean on your right. On some curves, the cliffs plunge several hundred feet into the water. You can see for miles and miles. You're cruising along at the speed limit, one hand on the wheel, sitting back, tunes blaring, and not a care in the world. You come around a bend in the road, and suddenly, without warning, there's a blanket of fog as thick as you've ever seen it.
