Pros:
Good confidence booster. Aces & birdies galore. Course plays in less than 20 minutes. It's better to have 9 baskets out there to offer some recreational activity than just another drainage ditch running through a subdivision.
Cons:
Like the title says: simple and easy. Not a wide variety of shots. Boring.
Other Thoughts:
If I lived in the neighborhood around the park, I'd be out there every day listening to the sound of birdie shots in the chains, but I'm not going to make the drive just to play there again.
