Pros:
Quick play
As long as you don't throw over the fence or into the pond, discs are easy to find.
A handful of technical throws (hole 9 in particular) give variety.
Cons:
Strong throwers need to beware of overshooting many of the holes, as the horse field or pond are both excellent spots to lose discs.
Short.
When I went, the playground, pond, and walking path had people on them, you have to be more worried about errant throws as there is not much space to err.
Other Thoughts:
Beautiful park.
Young trees might be more challenging and interesting in a few years.
