Did you have a coach for a high school history teacher that knew no more about history than what was in the text book? And he couldn't answer any questions if the answer wasn't in the back of the teacher's edition of the text book? If all the history you know is what's in the high school text books, you've been left with a distorted view of alot of events in our country's history. You've probably also missed out on alot of history too.
I like to look at history from "cause and affect" point of view. I know that sounds like the boring part of history, but that's how you really learn from history. Try studying the events that lead up to a certain event then look at the changes (good and bad) that came about because of that event. I like biographies too (though not as much). Most of the time we see great men in history as extraordinary men whose accomplishments are beyond the reach of us common men. Read their biographies, you'll come away with a different point of view.
The internet has a wealth of resources for the history buff, covering subjects that you will not find in the text books. I've tried to put together a list of links covering various subjects in different periods in U.S. history. If you know of a good link that I have missed let me know.
