All the players were warned beforehand that if they were in something sandy, it would probably be a hazard. And it wasn't excactly written with fine print either.

They can read, can't they?

That's just it. If the rule had said "all sandy areas are considered bunkers", I'd be with you 100%.

Given the area was completely covered with people, there were no rakes, and the rule only talked about 'areas designed as bunkers', I just don't see a clear way players could determine what was and wasn't considered a bunker.

No markers, no rakes, a large crowd, foot prints.

And a young player trying to focus and win after a tough finish in the U.S. Open.

How many of those who watched it looked at his lie and said to themselves "hey, he's in a bunker"?

Not many I'd bet, since you couldn't see his surroundings much with all the people.

What would a reasonable person assume based on what you saw on tv before he finished 18 and learned about the ruling?

I understand the rule, and I understand the ruling, but I don't think it was reasonable at all and I think Dustin got screwed.
