Ten years ago today was the great Northeast Blackout of 2003, which spanned eight states and two countries (United States and Canada) and left more than 50 million people without power.
We’ve compiled some iconic images of blackout. Although, a decade ago and a continent apart, we can’t help but see San Francisco in in these photos and if something similar were to happen here, that we would come together–not fall apart. We also encourage you to think about what you would do in the face of a major power outage (cue: grab some extra batteries and make sure you’ve got a flashlight, or two, in the house!).
