The story line of the PBS program could be cut in half but it is important because for most Americans it is ancient history and teaches two lessons about errors some want to repeat. First, that sometimes stuff happens that cause even good Bible believing church going hard working Baptists to NEED public welfare even if they hate accepting it. Second, that it can be fatal to ignore natural events and processes i.e. climate change and sucking down the Oglala Aquafir. (sp?) In the near future the oil wars will be joined by water wars.
