Since when did viewshed become important? This is such crap.
There's another "shed" buzzword that is even more bizzare, but it's so bizzare it won't come to me right now... You mussunt call it "crap" as these are sanctified words in their sanctimonious mindshed belief system, aka religion!!!
Gaia will strike you down and smite you for that!!!
At Yellowstone National Park, United Nations' delegates who surveyed the area last year, called for a "buffer zone" around the Park. So, the Park Service is choking off the local economy by refusing to maintain certain highways and by buying up any property available. Of course, there will be plenty available as more and more owners are denied the use of their own private property which causes businesses to shut down and the economy to show.
Inside Yellowstone, the Park Service is shutting down campgrounds as the park is being prepared to become the core of a huge biosphere reserve, as part of the United Nations global plan. Once established, no human activity will be permitted in the area. This represents fulfillment of plans outlined in the United Nation's Biodiversity Treaty - which, though still unratified by the U.S. Senate, is being implemented by the Clinton Administration.
