So, while not in the shape for this now (at 45) in my teens and 20's I went up to 24m in cliff diving (or off bridges, our fav was a 15 meter over deep water with a pedestrian walkway). This looks like a lot of fun, and wish I would have known something like this was "official" when I was doing it. It's not that I'm not scared of heights (I'm not though) it's that I don't have the human reasonable amount of caution in and around heights, even after several nasty falls.<br><br>These are the kind of things that yes people got hurt, but it was never me nor my friends so . . . IDK adolescent immortality complex kind of stuff, would not do it out into random quarry pools these days.,(reply>), Lucky.
