Changing world at night

As a geography geek I have always loved the "earth at night" picture.  It is a picture that reflects economic development around the world.  I love looking at the picture and identifying the major cities around the US.  A couple of months ago I saw a shocking new blur of lights in the area of North Dakota.  

In the past week this has become news on several websites. But if I had kept up blogging you could have read about it here first.  

I'm sorry for letting you down.
