In this very small park, you will find the smallest library in Hockessin, so you would be correct in assuming the cache hidden here is going to be very small too. Unlike most micros, this one should be an easy find for most cachers, unlike finding a micro hidden somewhere in a regular sized library.
Be sure to bring your own pen, and leave all your swag and trackables behind in your vehicle for another cache because this one will be too small. However if you are an avid reader you might want to bring a book you have read to exchange for a new one.
