Thread is here...
My responses in that thread pretty much show what I feel about the situation.
To summarize: I believe the safety steward acted negligently, and I have deep reservations that a Divisional Safety Steward took a look at the course. Unfortunately, the waiver and his particiaption in the event means he has no recourse.
From pictures from that event I have seen: there was a long straight that ended in sweeping turn and offset/lanechange maneuvers. Which is where most people went off. This case he went off driver's right.
It sucks, and hopefully his emails will get something done about it.
