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.
