This morning, as I was walking down the street—on one of those uber-hyphenated strolls that freelance journalists colorfully like to describe as the "are-you-kidding-I-can't-afford-to-take-a-cab" variety—I momentarily tripped across a small fissure in the concrete. And then I got to thinking about the 6.4 magnitude earthquake that rocked the Calaveras fault in California, back on July 1, 1911. Today, were that earthquake still alive and happening, it would be 100 years old. What a grand old dame it would be! I decided to put on my imagining hat.
