I've always had a fascination with ghost towns of the Old West. There's a rustic, old-world charm about the history they hold. But, there are similar forces at work today. It's hard to see sometimes, because it seems like there are so many people ... everywhere you turn. But it is happening in some places.

What's really interesting is seeing images of what these places look like now that they are being discarded. And, even wilder is that some of these will be destroyed to make way for new, more modern improvements. Check out the city in China, for example, just the character of the buildings speak of history. And yet ... they will be gone soon to welcome advancement. But will anyone want to come back? And what makes them come back?
