Tim DeChristopher has been in the news since December 2008, when the former University of Utah economics student bid $1.8 million on 13 parcels of BLM land in Utah at a federal oil and gas lease auction. DeChristopher had no plans to pay—it was a spontaneous act of civil disobedience to protest the sale of land near Arches and Canyonlands National Parks. The BLM took him to court; March 4, 2011, he was convicted of interfering with and making false representations at a government auction. He'll be sentenced to a maximum of 10 years in prison at the end of June. This weekend, he'll be attending Mountainfilm as a special guest and introducing Bidder 70, a film by Telluride residents Beth and George Gage. The 40-minute rough cut—a work in progress for obvious reasons—follows DeChristopher's rise to celebrity status among the climate change crowd. If you'll be at Mountainfilm, linger after the screening: Literary heavyweights Terry Tempest Williams and Bill McKibben will join DeChristopher onstage to discuss the current state of the climate change movement.
