Cons:
only 4 holes, all of which are short.
Other Thoughts:
As others have mentioned this is a good spot to introduce a kid to disc golf, perhaps a girlfriend, or another person that may not want to play a full course.
You can also use it to work on your midrange game, or experiment with some shots you may not want to bring out in a real round (roller, flick, tommy, etc.). Don't feel any need to play this course other than practice.
