[Data-modeling] help with parks & recreation

[Alec Flett]

A while back I started to model "Parks and recreation"

http://www.freebase.com/view/user/alecf/recreation

The goal is mainly very local parks to see if they have playgrounds,  
tennis courts, etc... I started with the parks in my town (Berkeley,  
CA, USA) and it looks like a few others have been added....

But I'd like some help flushing out some of the types..  anyone have  
any feedback?
