The one I references is number 63. Heh. The one I live in does not make the list.
The whole state is 25 people per mile. And if you stay clear of Vegas and Reno then that number is vastly lower.
If you were in Reno and wanted to drive to the north end of Washoe county... it would take you 5 hours. If you wanted to drive there while staying in the county... it would take you 8 hours! And a lot of the drive would be dirt roads.
