Demonstrators carry a giant mock pipeline while calling for the cancellation of the Keystone XL pipeline during a rally in front of the White House in Washington November 6, 2011. Protesters are unhappy about TransCanada Corp's plan to build the massive pipeline to transport crude from Alberta, Canada, to Texas. The Obama administration was poised January 18, 2012 to reject the Keystone pipeline proposal. REUTERS/Joshua Roberts/Files (UNITED STATES - Tags: POLITICS CIVIL UNREST ENERGY)
