I remember it well. It was the morning of the PSATs, and when the earthquake happened I was in the shower. I had never experienced an earthquake before, so I had no reference yet with which to compare my experience. I had always thought of an earthquake as a shaking of the ground, but that's not what this one was like. It felt as if the world tilted for a moment with a rumble, and then readjusted itself.
Needless to say, the earthquake was the talk of all the eleventh grade when we arrived at the school later that morning to take the PSATs.
By the way, today is also the nineteenth anniversary of Black Monday, the day in 1987 when the Dow-Jones fell 508 points.
