One day, you may be able to try out a zip line at Denver International Airport. Or a climbing wall. They're all part of a massive renovation plan for Denver International Airport's Jeppesen Terminal. That's the main building with the white peaks, before you get on the train to the other terminals.

Last week, Denver's city council gave the go-ahead to start discussions on the plan that would include a public-private partnership. Denver Post reporter Jon Murray is following developments. He spoke to Colorado Matters host Andrea Dukakis. Also, Monday, CPR's Michael Sakas explores the problems on RTD's A Line to the airport.
