CPR listeners have been sending us lots of questions about Denver's bid to land Amazon's second headquarters. We asked Gov. John Hickenlooper what concerns him about the Amazon deal. We also asked Hickenlooper if there's an issue he's faced in office that could threaten his political legacy. Then, how to design the modern office. We meet the architect behind Google's new complex in Boulder. Plus, 500 years ago, Martin Luther nailed his "95 Theses" to the door of a Catholic church in Germany and divided Christianity forever. How one church in Denver, where Catholics and Protestants pray, will mark the occasion. And, Boulder’s latest work in its experimental public art series comes from New York City artist Mary Mattingly.
