Just read the rules and everyone will 'be on the same page'.
It looks like someone tore up a phonebook in the CHILDREN's Playlot. Sure, there are park workers who come pick up the place, but this mess is deliberate, defiant and obnoxious. Just remember, everyone's mother and dad pay into the taxes that pay the park workers to pick up the trash.
If you're the mother or dad, then its time to read the sign. If one or two people get busted for littering it might stop.
There's been a lot of flap about the age and size of 'youth' in the park, not to mention the habachi people one weekend. This playground was designed/created for smaller children. That small scale table isn't for teenagers.
