Later, 8:58 pm: I just mentioned the earthquake to my wife. She feels "vindicated." Right after dinner, after I had left the dining room, my wife asked our daughter, "Do/did you feel that?" Our daughter had not. But my wife, a Californian, I guess, and hyper-sensitive to the earth's movements, had felt it. Hmmmm. I'm impressed. Comments to one story said it was felt as far south as Plymouth, MA, and Connecticut.
Said to have been felt in Boston. I didn't feel it.
