I was there.
I attended Arkansas Governors' School in 1992 when this was written (while X42 was running for Prez the first time). I don't have time to respond to all this right now, but I will say the truth is somewhere in the middle. The whole thing was slanted hard to the left, but it wasn't really brainwashing. Overall, I'd say it was a positive experience, but there were also obvious problems with the way it was structured.
If anyone has any particular questions you want a first-hand account on, fire away.
My first question is: Were prayers allowed?
