Dorbrook Recreation Area in Colts Neck, NJ is home of Challenger Playground and a Spraypark. It is wonderfully reviewed (as all playgrounds in New Jersey are) by my friends at NJ Playgrounds. If you are ever looking for a place to play in New Jersey, this is place to start. They review all types of play places, both indoor and outdoor.
