Huh?

I don't get it... I'm watching CNN, absolutely frantic reporting about the long gas lines in south Florida, but no one is saying where exactly all these people are going that they need gas? There is no power in most of the area, you can't possibly have to go to work unless you work in like a hospital or are a cop or something, so... where are they going? Why do they need gas in their cars right now? If they have enough to wait in that long a line, surely, they have enough to get to the grocery store if they have to. WTF?
