Potential Darwin Award Winners

That was the first thing that came to mind when I read this story:

"A 'no trespassing' sign warned four teenagers in Florida not to walk onto the railroad trestle where they were joking around and taking pictures. A fisherman along the banks of the creek below also told them to be careful. The final warning was the howling whistle of an oncoming train. They tried to heed the piercing alarm, but only one was able to sprint to safety.The other three, all girls, were struck and killed by the train Saturday."
