I used to listen to NPR a LOT. But I can't take "wait..wait.." It's a little too "High Brow" for me.
Car Talk used to be a lot better when they were local and actually talked about repairing cars. Since they went National (quite a while ago) it has gone less about actual car problems and more about humor. What really turned me off was that they even bothered to take a call from "Lexi, rhymes with Sexy" about a Lesbian custody fight over a Toyota truck. UGH. But they are funny guys. I met Tommy one time and he'll keep you laughing for hours! I love them, hate the show...
Morning Edition and All Things are GREAT shows. Over the years I have contributed to the local NPR stations to keep All Things on the air. It balances an afternoon of Rush Limbaugh...
And ya gotta love Michael Feldman and...er..."WHat's..." um, I forget... Oh, Whaddya Know?
But more often I listen to XM now.
