I had heard about Calico ghost town a couple of years ago, and had wanted to visit it since then. The only reason was that it has an odd building with lots of bottles on the facade.
Calico used to be an old mining town, but people left it when it no longer was profitable to mine silver there. Some guy later decided to restore a few of the buildings, and build some new ones in old style.
There's an entry fee of $7 per person, but it was free now since it was off season and close to closing time.
