I was living in Brooklyn, NY during the 2003 blackout that knocked out much of the northeastern US for a couple of days. In those days we weren't quite so dependent on cell phones and such things. People walked home, since the trains were stopped. Guys grabbed flashlights and directed traffic. We listened to the news on the car radio. After that I went to J&R and bought a wind-up emergency multi-band radio. In the intervening 22 years, I've never used it. Though at the rate things are going, maybe that will change.
