My local NPR station did the unthinkable over the last six months or so: They changed the schedule entirely. As a result, all the worst shows (by "worst" I mean shows that involve audience participation) are during the times I'm in the car.
I got desperate. First I turned to podcasts, which I love, but there are only so many one can listen to in a row before they all start to run together.
Next, I tried something I've always disliked: Audiobooks.
Audiobooks have never really worked for me--I'm not sure why, but I suspect that because my previous attempts at audiobooking were pre-iPod, so a lot of the listening was annoying on a technical level, with the messing with CDs and all. I also think I'd chosen the wrong types of books for audio, since if I recall correctly, I mostly chose long, complex books, which weren't the easiest for me to track in shorter chunks while operating a motorized vehicle.
But finally, I've found some audiobooks which worked for me.
I adored finishing the the wonderful Curse Workers series on audio. Jesse Eisenberg narrates and adds so much to Cassel's voice, actually making him sound more teenage and funny, which I didn't pick up in the first book, which I read in the traditional way.
I also loved listening to Catherine Gilbert Murdock's phenomenal Dairy Queen series (recommended by Flannery), which I'd actually started as an ebook a couple years ago and for some reason I couldn't get into (probably a wrong frame of mind thing). The narrator does a brilliant job of capturing both the Wisconsin accent and D.J.'s neurotic, self-deprecating tone.
