Video: Most big cities in the world grow over time; a few notable exceptions have sprouted pretty much out of nowhere. But for every Washington D.C, there are also vacant lots in the middle of the desert, waiting for residents who never came.

But the people never came; although a few thousand have settled (and there's always room for more!), it's really just a small town serving Edwards Air Force Base. It also serves as a stark reminder to would-be industrial planners: a pretty road infrastructure isn't everything. We're looking at you, Canberra.
