Ideally something:
Free to watch because I am a cheap bastard (will pay if its a REALLY good one)
Something interesting, like you watched it and learned things you didn't already know
Something that goes into the military strategy of the war and how it was won
And/or something that will make you feel good about the county (not that I don't, just something to make you realize how badass the founders were)
Thanks!
Library. Books, including audio books and free downloading, movies and documentaries. If your local Library does not have the one you are interested in, you can ask them to find one through the LIL ( Library inter loan)
