You guys all keep saying that 1997 was the first year of the pipe borders. I have proof in the form of a field blue print from Mystic design company in my archives that clearly shows that in 1997 there were no pipe borders - only 4x4.
So unless you want to count the human player barrier as the field border or they built the field not per print, which I don't remember happening (but then again I am getting older), then you guys must all be guessing.
