I was actually awake lying in bed when the quake struck. Felt like somebody climbed on the bed or something, kind of startled me a bit, not very severe here in Chicago though, it kind of reminded me of the last one I recall here in about 1986 or so. I wasn't sure exactly what it was at first, though maybe an upstairs tenant had jumped up and down or something, or something had happened in the neighborhood, I didn't realize it was a tremor at the time. I am sure it was a lot stronger south of here. Rich
