Pros:
It's a beautiful park. I used to play baseball here when I was a kid, and I have some great memories. There is a very nice stream running through, and some great views.
Cons:
You are constantly throwing at other players, walking paths, biking paths, over a walking bridge, at parked cars, and moving cars. Finding hole 1 is impossible, and is 200 yards from where you park. The 9 holes do not go in a circle, if you want to play a second 9, you have to walk 200 yards back to hole 1, crossing several holes in the process. Otherwise if you finish at 9, you have to walk 100 yards in the opposite direction back to the parking area.
Other Thoughts:
It's worth playing once, and maybe throwing together a picnic.
