Agreed. And I see they had spare clues attached to the side of the mountain, taking into account that some of them would be accidentally dropped/blown away.
Was the eliminated team the same one that ran around looking for lunch, not understanding that the bread in their backpack was actually food? (not that I'd eat the thing since it didn't appear to have been wrapped in anything to keep it clean)
As far as danger goes, I had a momentary thought: they'd probably never do it, but those cliffside board walkways attached to the mountains in China would be something to see. You have to be basically fearless to do that, though, and there wouldn't be room for any camera crew. Those boards are narrower than half the width of a normal sidewalk.
That bit of dialogue between the father and daughter was funny - about her saying she could get married in the church they passed, and him saying, "if you ever get your boyfriends sorted out." That gives the impression that he'd be relieved if she found someone - anyone - and just made a decision!
