I went to cliffs of moher in 2001? and there was just a simple guard rail there, you could go on the other side of it pretty easily, etc. My father went back last year and said it looks like a suicide prevention team camps the place, lots of ‘don’t jump, call us if you are depressed’ signs and more impressive barriers.
pretty sad.
On a more extreme side of this, I went to Gullfoss in iceland in january long ago, and there was just this ‘barrier of 1 foot stakes with a rope through them showing where you should not walk. Followed it up north along the west of the lower falls, up toward the upper falls, and just getting there, slipped on ice. didn’t slide, but if I had, that would have been that, presumably survival odds down that chasm into the lower falls would not have been good, given the temperature and possible rock impacts....
Ouch...glad you didn’t have to stay ‘extra time’ in Iceland from any injury. And the barriers on the Cliffs could still be easily broached...but there were signs up, Probably has to do with lawsuits that have been leveled against the place by families of jumpers. Sad...
