Christo and Jeanne-Claude come to Colorado to talk up their plans to cover a river. “The artists and their collaborators plan to stagger a total of 6.7 miles of fabric over 40 miles of the river, with interruptions ranging from 15 miles to a few hundred feet – the latter to accommodate trees, rocks and other encumbrances along the banks.The couple already has spent more than $2 million on the project, including a wind-tunnel test of the fabric and a simulated installation of several of the panels over a river running through a ranch near Grand Junction.”
