In my own experience driving for a little while around the Four Corners area in the desert, there were more than a few spots where the only option was NPR, because all other stations on the dial were glassy-eyed christian proselytising, especially driving Utah -> Colorado. I mean, the kind of radio that even normal christians would be uncomfortable listening to. I like NPR's content anyway, but if you lived in some of those areas, it's the only option that isn't cult-ish.
Unfortunately many of these Christian stations have poorly maintained transmitters that broadcast not only on their assigned frequencies but also all over the adjacent NPR stations. Only Christian stations seem to get away with this.
