On a clear day, you often can see for miles and miles. But as a report from the National Parks Conservation Association points out, clear days are harder and harder to find in our national parks under the Bush administration's relatively laissez-faire approach to coal-fired power plants.

Great Basin National Park, which boasts the cleanest air of any park in the Lower 48, could lose that distinction if a coal-fired power plant is allowed to go on-line as proposed just 38 miles northwest of the park.
