Probably when some freaknut tried to get to close. Hopefully it's electrified.
Youtube has some "freaknuts" being called out by the sentinel. Good stuff. I find it amazing as to how stupid some people are at such places. I remember being on the road between Little Round Top and Devil's Den when a bus load of school kids got off and started tossing a frisbee. It was brought to the chaperon's attention that this sort of behavior in that place was unacceptable. It stopped.
