Bleagh, I lost this entry because of kerberos. Specifically, because the backend server for this blog engine couldn't talk to the frontend: their clocks had skewed. For kerberos, which depends on a 5-minute window (which in itself is kind of hokey, if you ask me), this didn't hold water. The webserver refused to coöperate, and I had to manually reset the clock yesterday. In the mean-time, the POST had expired from my machine's cache. Grumble.

The post was about the relative cost of traffic infrastructure in Seattle, Phoenix, and San Francisco. Per mile, the 2km Caltrain extension weighs in at an order of magnitude more ($1.5 bln) than the $180 mln/mi Seattle light-rail; Phoenix is developing a multimodal approach, which includes long-term traffic planning, highways, and a possible light rail.
