I don't know if anyone's mentioned this before, but every time I look at the memorial..tower water fall holes...I always ask myself what will happen to someone if they fall in there? People may fall in there for all sorts of reasons..fooling around, 'stunt men', suicides [I really hope not..], and just plain crazy lunatics. I see that pit/trench, but still people are inventive.
My first glance of the holes is that its a hazard. I'm all for making a memorial to commemorate the victims, but this is just one part of it I don't understand.
