I found this documentary on YouTube and it is very interesting, there are even bits about Lincoln in there, if you have the time I recommend watching it. The sound quality in like the first 30 seconds isn't that good but it gets better for the rest of the video. [video=youtube;jPh4mPnzyh4]https://www.youtube.com/watch?v=jPh4mPnzyh4[/video]
