To be fair, where else are you going to go? There are other stations that have news-like content featuring talk show hosts (no judgment, well, maybe a little), but the NPR and Arizona Public Media programming on KUAZ is available, interesting and intelligent. Plus, a couple times a day, you can hear the dulcet tones of Kai Ryssdal talking about money. What more can you ask for?
