I've lived in Southern Cali all my life, nearly 52 years and have felt lots of em'.
The last one we had (that I felt) was about 2 months ago. My wife jumped up out of bed,( it was about 6:30am) and ran to the doorway, I just stayed in bed, and teased her about how that was nothing, and she was starting to act like a tourist.
But back in the late '90s the Landers quake scared the bugeebies out of me, I almost set my bed up outside, Its an awfully weird feeling when it happens. You almost always look at each other like, Do you feel that? Its almost like you don't believe it or your not sure whats going on. The small ones are kinda fun though
What Gerry says is exactly right.
