Query: Must see video

This film portrays a courageous patriot who has "walked the walk" for over 30 years. So many safety issues we take for granted (seat belts, car seats, tire standards, and more) were initiated or pushed by Mr. Nader. The film is inspiring and challenges us even today. This should be required viewing for every high school senior.
