The Audio Books site is offering punters a free Ayn Rand audio book. How cool is that!
Choose one of either Philosophy: Who Needs It?, The Virtue of Selfishness, or Atlas Shrugged, which would be a very long listen indeed -- although as this YouTube presentation using the Atlas audio book indicates, a damn good listen.
Just the sort of thing you'd want to listen to while touring the country by Winnebago.
UPDATE: My spies tell me the book is free only if you cancel your order within fourteen days of downloading. So be careful out there.
