We'll admit it: Arizona's DUI crackdown has us depressed. Seems you can get arrested just for thinking about booze these days — for daring to actually drink a glass of beer, we've heard, you can face the death penalty. And it's not just the thousands of drivers who've gotten popped who are talking about the issue; it's the restaurants and bars, the cops, the lawyers. But leave it to Ken Sharp to bring everybody together to have that conversation on the air. Sharp, who used to facilitate court-ordered group discussions for drunk drivers, got the idea to build a radio show around the DUI topic, and after a Friday-night launch, was soon airing his show each weekday during the lunch hour on KFNX 1100-AM. The discussion has been fascinating and intensely real. This fall, Sharp intends to launch the show on a different station, so stay tuned for details. With the way things are going in this state, you really can't afford not to listen.
