I was at home (in Brookline, Massachusetts) on the computer when the phone rang. It was my younger brother, Josh, in New York Cty, calling to ask me if I knew what was going on. As I had left the TV news on in the living room, and the TiVo was recording its buffer, I was able to start describing the news to him and I learned of the blackout as I told him what was going on.
I served as the point person for my younger brother, my sister-in-law, and my mother for the next few hours. Josh had to sleep overnight in Manhattan. Rachel had to care for their new baby daughter, and I gave her information on New York City emergency lines and hospitals. And my Mom stayed home.
