I am what you call a Road Warrior, in the sense that my commute to work is two (2) hours one way using the oh so lovely mass transit system the Metro with a shuttle bus thrown in at the end. Never the less that turn into 4 hours at minimum of possible study time, if I use my time wisely. I am also a Software Architect by day and Photographer by night. Needless to say I have a lot of quite time were I would love to use to listen to audio version of PMP Exam Prep. I am on the computer all day for 10 hours or so once I get to work and then the commute starts again.

My question is simply I already have PM PrepCast which I love but I want to add one or two other audio programs to the mix so that I can play ninja mind tricks on my memory and learn the content by switching it buy listening to one program on the way to work, then another program on the way home and then another program while I am at my desk.

What audio programs have you guys used in the past or that you are using now that  you would suggest I get.

When it comes to books I use them once I get home but I spend most of my time on the move. If there was a audio version of the PMBOK I would like to know that as well, but I am sure that is more or less a very dry listen.
