The Olympic Stadium floodlights cast their light over a snowy scene after they were officially switched on by Britain's Prime Minister David Cameron at the Olympic Park in Stratford, London, Monday Dec. 20, 2010. Prime Minister Cameron pushed a button that switched on the towering floodlights over the snow-covered stadium in east London on Monday evening. London Mayor Boris Johnson, Olympic organizing chief Sebastian Coe and dozens of local schoolchildren were among those attending the ceremony in freezing temperatures inside the mostly empty 80,000-capacity stadium.
