Man, we got absolutely nuked by the derecho in 2011. I was living in Falls Church near I-495 at the time and my neighborhood was lit up by that beast. I will never forget the sky looking like that - purple, black, swirling, words do not do it justice. There were transformers blowing everywhere and constant lightning and it looked like the fourth of July.
Folks in my office at the time, particularly those in the Bethesda area, were out of power for up to two weeks.
At the time I bailed out and drove to PA for the weekend to stay with family. It was on a Friday night, right? Came back when the power was back on in the nhood.
