All the internet debates I saw when the confederate flag came down got me really interested in how so many people could know TOTALLY different things about the most historically significant event in the country.
Now I've got about 12 books covering things in different ways (and there are so many more). Thanks to the Library of Congress and Google's efforts to scan books it's really easy to check citations as you read when you're having those "There is no way that's real" moments followed by "Holy crap! That's real?!?!"
The whole thing has sparked an overzealous interest in history, which is the subject that interested me the least when I was younger. Now I give serious consideration to pursuing a doctorate one day with the aim of being a History professor when I get closer to 50 (which is still a decade or so off).
