PAST the neon lights of Reno and the cookie-cutter homes of neighbouring Sparks, the I-80 highway winds through a thinly populated expanse of arid hills and lunar valleys in Storey County. On one side of the road flows the Truckee River; on the other bands of wild horses forage for parched grass. Signs of civilisation are restricted to electricity pylons and the odd rundown farmhouse. The Wild Horse Saloon, a dark and smoky room connected to a legal brothel, is the only sit-down restaurant for miles. It is not an area that immediately seems conducive to hosting a business park. Yet Storey County in Nevada is home to the world’s largest by some measures: the Reno Tahoe Industrial Centre (TRI). The park spans 104,000 acres in total—three times the size of San Francisco.
