I have to train WHO?
The River of Wealth and Freedom. Presented by GMC and the American Trucking Association Foundation.
Found on side 2 of the 1978 GMC Truck DiscoVision / Laserdisk. An interesting look at women in the workplace in the late 1970s, and a nice snapshot of what the highways looked like almost 40 years ago.
Sadly there is a bit of LaserRot, especially at the beginning of the film.
