I just watched the WDAY TV film documentary of the Fargo event. Besides the nostalgia hit (the slicked back hair, suits and the formal speech and presentation which were still normal in my earliest memories of TV during the 1960's), it is interesting to see how the event was recorded by some early storm chasers from the University of Illinois and the then US Weather Bureau. Given the technology limitations at the time, they managed to obtain an excellent record of the passage of the tornado through Fargo. I have bookmarked this website so that i can go back and look at more when I have the time.
