there wasn't an accident or? Anyways parks here are always over crowded. Even if they are to install another ten more play areas at the Aspire, rest assured they will all be packed up in a jiffy, specially come weekends.
As for accidents then yes, they are inevitable at most if not all playgrounds. Kids will be kids and all that plus with overcrowding on slides and climbing equipment. Utter chaos! Which is why I can't bare to go anywhere close to em on weekend nights. If nothin else then I can't think of anything more lethal than an eye full of sand flung from an overly "playful" kid *shudders*

PS: Noticed I never used the word "playground" more than once!
