Hoping to give himself a green sheen, President Bush traveled to Rocky Mountain National Park yesterday to engage in trail work for a few minutes and talk about character. “There’s a grand vision embodied in these mountains,” he said. “And the vision is that we can teach our children right from wrong.” He also criticized environmentalists who are concerned that fire management plans might be used by the Bush administration to boost logging levels on federal lands. Bush said, “I know there are some in our country who want to just, you know, let the forests fall apart. We’re not going to let that happen in this administration.” More than 125 protesters greeted Bush, waving signs calling for more wilderness protection and no drilling in the Arctic National Wildlife Refuge in Alaska.
