Granny stops grader

Granny graderOklahoma grandmother Nancy Zorn, 79, was taken into police custody after locking herself to a piece of heavy machinery, effectively halting construction on TransCanada’s Keystone XL 4,000-mile tar sands pipeline from Alberta to the Texas Gulf coast. Protests by First Nations and others in Canada and the U.S. have escalated following several spills, including one in Mayflower, Arkansas where an estimated 80,000 gallons of tar sands spilled into a residential neighborhood and local waterways.
