The short video of the civil war battles is located at the new Abraham Lincoln Pres. Library and Museum in Springfield, IL. The video is shown on a large screen ( 10' X 12') and it is moving!!! Right behind where you stand to watch the video, is a large display of pictures of the civil war.
If you and Jan haven't seen the Abe Lincoln Pres. library and museum, you should. Like all museums there are weak areas, some look like a Disney project, but over all it is a good one from my viewpoint. It is a popular place for school kids.
Maybe it's the music that gets to you. It could be related to a Time article I just read about "Sacred Harp" music and its revival. (Listen to the podcast)
