Another reason high-speed rail is a great idea

From Matt Yglesias at ThinkProgress:

For example, today there seem to be almost 30 flights daily between Seattle and Portland. Clearly a lot of people are making the trip. If you built a high-speed rail connection, a lot of people would take that. But how many would obviously depend heavily on how the price compared to the price of those flights. And that in turn would have a great deal to do with how we price pollution.
