Proposed Keystone XL Pipeline To Run From Canada To Gulf Of Mexico

POLK, NE - OCTOBER 11: A wooden post marks the precise spot where the proposed Keystone XL pipeline would pass through Shannon Graves' property, on October 11, 2014 in Polk, Nebraska. Graves, a native Nebraskan, is staunchly against the proposed Keystone XL pipeline, which would pass through her property. She believes the pipeline would negatively effect Nebraska's environment and is frustrated by the way TransCanada has treated Nebraskans. (Photo by Andrew Burton/Getty Images)
