Congratulations on finishing Pimsleur, Lylandra. I've nearly finished myself, and I've been wondering the same thing. While Russian radio, TV, etc. are excellent resources, they're not really an option during the daily commute to work (and I haven't found a native Russian to carpool with yet ).

I have a 45 minute drive each way, and Pimsleur has helped to make that time productive. More importantly, no matter how busy I get, there's nothing else to do during the drive, so unlike my studies at home my Pimsleur lessons have never slipped. So, it would be nice to have something to fill that void. It seems that the best thing would be audiobooks. Preferably, it would be something at a fairly low level -- children's books, perhaps.
