In Minnesota and Wisconsin I will listen to public radio. There are a lot of good stations. In the south the radio goes off. I listen to podcasts on my iPod all the time. You can get many for free off of iTunes. I listen to several public radio shows, my favorite is This American Life. I also listen to a lot of stand alone podcasts. I have a backlog of about 200 podcasts which I probably will never get through. In one car I have to use an adapter to play the iPod through the radio. The newer car has a plug in.
