Earthquake

Last night we had an earthquake in Central Illinois. The second largest on record. I slept through it but my wife was up and said things were shaking and rattling pretty good. I just felt an aftershock, and it's the only quake I can every remember feeling. We just don't get them around here, at least not anything you'd notice.
