David Dean: Do you propose we start with the transit option with the highest externalized cost?

JK: First you should start with credible data, from a well respected journal such as ACCESS (NUMBER 1 6 • SPRING 2000), (instead of crap from an extremist web site):
The article is at : americandreamcoalition.org/transit/Delucchi.pdf
A summary is at: DebunkingPortland.com/Roads/Docs/Delucchi_Chart.htm
PS: google for Access magazine and you will find the whole Spring 2000 issue)

I suggest you add it to your reading list, as it is a well respected information source, unlike much that is posted here.

Thanks
JK
