For the book lovers out there who travel, have you heard of the free website "librivox.org"?
http://librivox.org/
It's a free website for downloading online classic books into MP3 or CD format. It's a great way to fill in that commuting time when the radio stations get monotonous.
It is interesting to have different chapters done by different people. I've been able to get through about a book and a half a week this way with all the travel I do.
