One teensy little thing though... For those of y'all who keep mentioning underground trains, it would never work. Much of Houston was built on swampland, remember?

He was right in the article when he said that Metro's ridership is dismal. Driving around every day, (I drive for a living.) I hardly ever see a full city route bus. They just don't happen. Yes, the P&R buses get utilized, (somewhat) but that's a different kettle of fish.
