I was in a dept meeting when it happened. My boss was going over the agenda and we were all sitting in a circle and I felt the ground shake. At first, I thought it was the construction going on then the lights flickered so immediately, I knew but didnt react until it was confirmed. My son's daycare said that the whole building was literally shaking back and forth and the cars in the parking lot were rocking hard sideways. I dont know about Mac..he is trying to get home but trains are running on reduced speed from Washington, DC where he works at.
