Koch Billionaire Builds Private 'Old West' Town Bill Koch reserves town for friends, family, and historians By Neal Colgrass, Newser Staff Posted Aug 20, 2012 4:40 PM CDT Updated Aug 20, 2012 5:05 PM CDT 47 comments Comments An Old West town.

The replica Old West town is billionaire Bill Koch's ode to a pricey obsession: American frontier memorabilia. Built on Koch's 6,400-acre Bear Ranch property, the town includes board sidewalks, polished brass, and a water-treatment system, the Denver Post reports. It also has a locked gate and guards—because it's never open to the public. The town is only for the Koch family and friends—and historians—to treat as their plaything. "It's like something out of a 'Gunsmoke' movie set," says a county planner. Known as "Wild Bill" to his friends, Koch is worth around $4 billion and is brother to David and Charles Koch, billionaires famous for their Tea Party politics. But Bill is known for collecting wine, winning America's Cup, and writing multi-million-dollar checks for photos of old gunslingers. His wife tells him he belongs on TV—if the show Hoarders will take him.
