It is not exactly Charlie Brown Thanksgiving, but do yourself a favor and watch the documentary The Big Uneasy about the failures of the Army Corps of Engineers that had much to do with the catastrophe that was Katrina. The film was made by, of all people, Harry Shearer of Spinal Tap and The Simpsons fame. But the film is highly educational and slightly infuriating. If you do Netflix Watch Instantly it is there. It is also available to Amazon Prime members. If you are not a member of Amazon Prime you can watch the film for $3.99. It is $4.99 on Itunes.
