Just saw The American Blackout 2013 National Geographic(on YouTube). It was really good. It reminded me of the situation I was in when I worked in Florida for one winter. I felt uneasy the whole time because I had no way to survive other than what came in on a Walmart or Publix truck. Couldn't wait to get out of there. Most people have very little in the way of extra food or water, and if you depend on the infrastructure you are just out of luck. Lots of people are going to die sooner than they expect to.
