Greenpeace and Chesapeake Climate activists hold banners for the Strike Out Exxon at Nationals Park campaign during a Nationals game against the New York Mets in Washington, D.C., September 15, 2008. The campaign has been keeping the heat on the Nationals management, being a presence at every home Nationals game since June 20th to discourage consideration of ExxonMobil for the naming rights to the first green ballpark in the United States. Activists dropped banners in the scoreboard area at the end of the fourth inning of the game after ExxonMobil advertising was displayed on the electronic signboards in the new stadium.
