My suspicion, based entirely on rumblings and the whole faux Munch press release nonsense a few weeks back, is that Munch and/or Sanderson were trying to broker some kind of deal and they just happen to be ACE members, and thus it came into the conversation as if they were doing something on the club's behalf. That's one theory, again, based on a lot of whispers and chatter among people I don't entirely trust. I don't believe that Norton is saying anything they don't believe to be true based on the information provided to them.
That said, if I were an ACE member, I'd be asking a lot of questions too, not the least of which was any kind of official statement, even if it is, "We have no idea what Norton is talking about, and by the way, we did or didn't try to work with Cedar Fair to save the ride." Without that kind of statement, the club is thrown back into the Usenet nonsense of the last decade regarding its lack of transparency between its elected officials and its constituency.
