The above link will take you to an article on the old electric map... Now I for one would like to see this thing saved and re-displayed. Actually I have always found it a better tool then what passes for explanation in the new Visitor Center at Gettysburg. It gives one a true sense of a couple of things.
1.) The vastness of the battlefield.
2.) How close it was to a Confederate Victory.
3.) The heroic efforts on both sides. And the different keys to it.
So I am in favor of finding a way to save this. There was a time when I was thinking about getting involved in trying to save it. But was discouraged from it. But hey, if the GPMA wants to.. GO FOR IT!!!!!!
