Pros:
The park is huge and well manicured with many amenities. The course itself is well maintained, and pretty easy for beginners, like myself. You can get free equipment if you stop by the Basking Ridge Recreation Center nearby. There are plenty of things to do if others in your party aren't playing. Huge play area for kids.
Cons:
Gnats...lots of them! The entire park is full of gnats for whatever reason...they'll be in your face all day. Not much of a problem, but very annoying if you hate that sort of thing. Other paths in the park either cross the course or pass close by, so you have to wait for others to get out of the way before you throw.
