I mainly object to the letter "Walls Work" and opponents know it and who couldn't love a wall?
When what is now Great Salt Lake Mineral was first built by Lithium Corporation it was a joint venture with a German Company. I was supervising their chemistry lab at the time. They sent us several lab technicians from Germany. At least two lived in Hanover, West Germany. Their extended families had a farm that was divided into East and West Germany.
At first the family in the West would acknowledge the family in the East when they saw them in the fields. Finally the Eastern family got a message to the Western part of the family to please stop waving or calling to them. Whenever this happened the Eastern family would be taken in for extensive interrogation by the East German Communist government.
