If you're like us, you listen to KUAZ pretty much all of the time. Even driving across town in rush-hour traffic is entertaining and educational when you're listening to NPR bring you breaking news and timely interviews with movers and shakers. And on the weekend, a little humor in your news with Wait Wait...Don't Tell Me! or Radiolab make a drive to Mount Lemmon A-OK.
