Ya know, I've taken a few tries at audio books, and given that I spend every other week on the highway, sometimes in areas where no radio signal will reach, you'd think I could really get into them, but I can't. Something about the readers doing multiple voices that I just can't get past.
My wife on the other hand can't get enough of them. She always has audio books on loan from the library, and even if she is in the car for a 5 minute trip, she has to listen to a chapter or 2.
