Philadelphia Inquirer: Scientists Hail the Bus as the Greenest Way to GO

From The Philadelphia Inquirer:

The last time I took a trip on a bus, it wasn't pretty. It was merely cheap.  But that was a few decades ago, and now I have good reason to try again.  In a 54-page data-laden study, the Union of Concerned Scientists has concluded that traveling by bus - or, as they term it, motorcoach - is the greenest option.  In every scenario they calculated - from a single person going 100 miles to four people going 1,000 miles - the bus was better.
