If something like that were in a place I was visiting, I would probably go to it, but I would not use it as a reason to go to a particular area.In Arizona, there are two that I have been to:
Goldfield near Phoenix which is a reproduction of an old mining town in which most of the buildings were moved to this location from an old town nearby. They had to move because the original mine became flooded, but there is a reproduction of the mine there too.And
Old Tuscon Studios, near Tucson, which is a movie set that is a reproduction of an old west town and has been used in many movies and TV shows, and is still being used. The most recent movie I know of that was filmed there is To Kill A Memory (Freewill Films) which wrapped filming on June 1, 2011.
