Here's a link to an article that says an earthquake was felt in our suburb at 4 a.m. The epicenter was approximately 30 miles northwest of us. I don't remember anything unusual around then (or even know if I was awakened, since I try not to look at the clock when I get up in the middle of the night). In fact, the first I heard of it was from my co-worker when I got to work. I did, however, hear and see the lights from the snow plow up and down my street several times.
