To the contrary side, I have seen women in HIGH HEELS at the bottom of a hiking trail on Mount Monadnock in NH once. I wonder how far she got before she turned around. The pictures show a couple of "city" people. If you know what I mean.
I guess getting too close to the edge does happen, but this seems like a story I have heard more than a few times.
I think if it was a couple of friends or kids involved I would be more inclined to believe a tragic accident.
But a married couple arouses my suspicion meter. I, at least, would not accept the story at face value.
