In ITunes, search for "University of North Dakota".

UND has put video ground school lessons up for free! My Ipod is audio
only, but I watch the lessons on my PC. Video Ipod owners can obviously
take the video with them.

Take a look! The videos even feature commercial maneuvers.

Anit-spam disclaimer: I don't have anything to do with UND, Apple,
etc... This is posted only to share something I thought is ineteresting.
