I have a nasty habit of assuming that anything like a bang or rumble that I feel is a truck. A truck backing into something, a truck going by, a truck changing gears…doesn’t matter. I have mistaken a plane flying into the Pentagon 1.5 miles away and a bomb in Budapest only a block away as varying forms of truck noise. It’s only afterwards that I figure out what it is.

OK, so this time, I assumed it was people moving furniture or doing something else weird, but, unusual for these parts, there was a magnitude 4.5 earthquake 45 miles up the James River from Richmond, VA.

A friend IMed me a half-hour later and clued me in to what it was.

At least I didn’t think it was a truck.
