My post on another thread from yesterday:
"Just spoke with a friend who works on the train. He's not a boater, but has been down there with me a bunch. He said there was still a significant amount of ice, but he thought you could get a raft through, but it would be tight in some places.
The guy exaggerates a lot, and isn't a boater, so if he says he thinks a boat might squeak through, I'd be a bit nervous to go on just that. On the other hand, Bighorn is almost totally clear of ice as of this afternoon. . .
