mmcrea I'm surprised that this series isn't better known. I'm a geography instructor at the community college level, and I use portions of this series in class, or larger portions for bonus credit, because it is both an excellent example of all facets of migration patterns and processes, and because it's such an important part of U.S. history. The causes and consequences of this migration story tie into so many facets of our nation's development that it seems to me that this should be required viewing in American high schools. It is much too long to use in class, or even to expect someone to watch in one or two sittings, which is why I give it a 9 instead of a 10. It is well narrated by Morgan Freeman, the historical photos and footage are fascinating, and the people selected for interviews are charming, gentle, humorous, feisty, intelligent, courageous and dignified. It's as good as a Ken Burns documentary, and probably more important.
