I remember one in college that was a minor one--4.1 or something like that. Thing was, it was at 5:30 in the morning. I remember thinking to myself, "What's that shaking? . . . Oh, it's just an earthquake." Then, said message registered in my mind, and my eyes snapped open, with the thought, "Earthquake!" And I was out of my room in a flash.
I was on I-87 coming back to Albany when WRVE mentioned an earthquake happening in DC. My wife called me 20 minutes later and told me that her building in downtown Albany had been evacuated. I told her that if I was her, I'd just go to the parking garage and go home (she didn't). I pulled into the lot of my building in Albany and people were just filtering back in. It was 2:35. Ten minutes later, the guy who hired me (and is retiring at the end of September) came through, telling us, "Go home--the message just came down from on high."
Seeing that Irene is coming for the weekend, it should be interesting.
