William Harrison Hardy had a good gig going. He owned businesses in a town named for him: Hardyville (present day Bullhead City.) He also owned an important and well used ferry service at that point and a tollroad that led to Prescott. Soon he started opening businesses there that were successful, but in late 1866, he abruptly started to sell off all his interests in the Mile High City.
In 1901 at age 77, he revealed why to the Journal-Miner newspaper.
