4th grade! I was going to try the 5th grade but then I got my draft notice....
The Looming Tower deals a bit with this. If you haven't got it, I highly recommend it. I really obsess on this kind of stuff and this is one of the best accounts that I've read. Lots of fact, heavily footnoted + the guy can write, it's a real page turner.
Funny. :)
Thanks for the reccommendation. Interesting looking book.
