ive listened to thousands of audio books over the years, love reading but didnt have the time so this was a close second, used to listen when i was out walking or fishing or when i was doing stuff round the house, ive got speakers built into my bike helmet and tried listening on long journeys but had to revert back to listening to music instead, didnt feel safe concentrating on the book or more importantly the road , didnt work for me at night as i was falling asleep, the problem was finding my "Page" as the book carried on going when i fell asleep and it was difficult to find were i was when i nodded off. sadly nowadays i havent even the time to listen to audio books .
my favorite audio book was the pillers of the earth by Ken Follet, 45 hours long an epic, the follow up world without end was good too and only 35 hours long
