Wow, I'll bet that was chilling. I didn't know that they left all those people's bones out there after Pol Pot's ouster in the mid-1980s. Did you read Survival in the Killing Fields per my suggestion?
I have not yet, but I did get Children of Cambodias Killing Fields. The bones are not sitting outside in the fields; they are in a strange aquarium/temple looking thing. It is hard to look at. ]
I actually started reading Flyboys instead (I think you are the person who suggested that to me) and am almost done. I feel a little funny reading it while here in Japan, but I didn:t expect to come this way so it was not planned. no harm no foul.
