In the summer of 2018, Brent Underwood got a text in the middle of the night from a friend saying, "Look at this ghost town for sale!" Within a month, Brent had purchased Cerro Gordo, California, an abandoned silver mining town, with the help of friends and investors. He wants to revive the town for visitors while preserving its history. He's already faced some major setbacks -- from the lack of running water, to getting snowed in there during a global pandemic. But he calls Cerro Gordo his "life's work."
