Have you ever visited a "Ghost Town"?

A once prosperous town where all the inhabitants have left, but the structures are still standing?

Is it an American phenomenon, America being a relatively new country?

Did you enjoy the experience? If you’ve been to more than one Ghost Town, which was your personal best?

It’s on my ‘to do’ list. I love the Southwestern US, and I think I’d like to take a mini tour of Ghost Towns.
