I found an amazing new source for audio CD books. Ebay. I cannot believe I did not think of this before. I am going to start loading up on these things so I have books for my walks. I was going to save the audio books for just my walks, but there are so many available and they are so cheap, Lorena and I are planning to listen to one on our 10+ hour drive to Nebraska and back. These books make my daily walks much more enjoyable.
