People attend the U.S. Capitol Christmas Tree lighting ceremony on the West Front of the U.S. Capitol Dec. 7, 2010 in Washington, DC. This year's tree, a 67-foot Engelmann spruce, came from Wyoming's Bridger-Teton National Forest. As part of the U.S. Capitol's commitment to save energy, strands of energy-efficient LED lights and hand-made ornaments made by Wyoming residents decorate the tree.
