I agree with you that air travel is bad for the climate--I wish more business could be done by Skype, for instance, but that culture is slow to change.

I don't think Eugene having a nicer airport plays a part in most people's decision to fly or not fly. It just changes if they are going to drive to Portland or not. Which is worse for emissions--driving to Portland then flying to San Francisco or flying a shorter distance and not driving by flying out of EUG?
