Dubai--the MOST amazing city on the planet.

I'm endlessly fascinated with Dubai. A city with a huge skyline that just a few decades ago was a vast desert wasteland.

This great video was posted on CNN and shows the opening of the Dubia metro line. So take a ride and see this amazingly vibrant city that is growing at an astonishing rate. As you watch, just think about the fact that NONE of this was here 30 or 40 years ago.
