Beautiful Marley Park... a great place to visit on a cool, clear, crisp day. But there aren't nearly enough caches hidden here!
GZ sees you confronted with a grid of small trees in the early stages of development. The cache is hidden near/on one of them.
And it is disguised...! 
Be aware of the park closing times - usually 8pm in Summer and 5pm in Winter.
