Pros:
Great use of otherwise wasted wooded area on the end of a park. Despite being very short, they've done a good job of making the lines from tee to basket require some technical skill to avoid trees or work around corners. It's also free, easily accessed and so far seems well maintained.
Cons:
Very short and the tee's are just ground markers on the grass.
Other Thoughts:
Nice to have any new free courses, and it's a good way to work on essentially approach shots if you're more experienced while also giving new players a good idea of the game.
