The park was on my commute route home for years and I would stop there a lot, long before its infamy. It was a, ummmm, good choice for such a task. Amazing how something so close to heavy traffic could be so private...
Yes, I've been there too, just to see for myself. Even brought home a souvenir pebble :-) How VF's suicide trainers found the place themselves is beyond me. How various committees reached the verdict of suicide is no mystery at all.
