I live in southern Illinois and it woke me up. I lived in San Fransisco for a year and never had one while I was there.It's funny that I now live in southern Illinois and now I felt one!
The weird thing is is last night was my feeding night and neither of my snakes even came out of their hides to feed. witch is odd because nothing has changed husbandry wise. I was wondering do you think they sensed something was coming? I know they say animals can sense things long before humans but I don't know if earthquakes are one of them? weird stuff.
