several years ago i started to read Huckleberry Finn... but the dialect was too difficult for me to read and understand at the same time, so i decided to listen to it on audio... and it was wonderful!
I too love audio books because I have issues with my vision but lately have enjoyed my Kindle a great deal. I feel like I need to be moving when I listen to an audio book. If not, I sometimes fall asleep. I realized the advantage of audiobooks when I was rereading the Tony Hillerman mysteries. He does a credible job describing the wonderful southwestern landscapes but I had always skipped over that to get to the story. Now I listen to it all. Same with the Aubrey and Materin Master and Commander books. I will listen to the long descriptions of the rigging etc when before I skipped over it. I also find that I can listen to books about theology and physics while I walk (I walk a lot) and get about 60% of the meaning. If I try to actually read it I get bogged down and bored.
