Ok so I know what happened now. I heard the episode from B&B and thought it sounded exactly how I remembered it which would not be likely if I heard it here. Then I searched for Marble Mountains on the forum and found someone had put up a link some time ago. I believe I may have clicked on it before and listened to it while dozing off in bed. Sorry for the confusion. If you have not heard it though it is a great recount of an encounter.
