I looked at the pics, the cemetary looks very peaceful. I didnt see the playground you mention though.
Spiky, my father died when I was 16 - I havent forgotten him at all - I think you're all getting a bit blinded by your emotions and didnt see what I was trying to say.
I'm not saying if its right or wrong to build on it but at some point you have to accept tragedies, put them behind you and move on. You can't mourn people forever. Capitalising on a tragedy however is something entirely different.
