Junior Paper

Sooooo, In order to pass junior year in the state of Colorado you have to show that you're capable of doing research on your own. Hence, the Junior paper. Its huge and long and completely unnecessary but hey- thats school for ya, huh ?
Anyhow. It has to be atleast 1500 words (Which, granted, isn't even all that bad..) and I haven't a clue on what topic to choose and where to start.. any ideas?
