LongMetal....... Good Post...... You hit the nail on the head. A good story following your thought, In 1898 the President of the United States Patent Department wrote Congress to save money, do away with the Patent Dept............ He said, "Everything that could be invented, HAD been Invented"........... All the rest is History............ I would like to see these tree huggers living without the comforts of Engineering..... Thanks for the thought LongMetal............
