I just watched the new Discovery channel series "Perfect Disaster". They aired the first two episodes..."Super Tornado" and "Solar Storm". Geez, between this and the other super-disaster shows I have seen (ie-Super volcano in Yellowstone or Megaquake) I am afraid to leave my house. I might have to go and build a big shelter for my family. Did anyone else see these shows? The one with the Solar Storm was very interesting. Seems like if they even think something that big is going to hit. Don't take the risk..shut down the grid. I'd rather have a few hours of inconvenience than months or even years for power to return.
