Pros:
Justin Trails is a course that is fairly open in many parts, owing to the farmland it is situated on, but offers startling and breathtaking elevation changes (you can see for miles). Once you graduate from the first few open holes, you will face a variety of tunnel shots that are complicated by severe slope in both R to L and L to R orientations. There is a pond to navigate from an elevated tee, which makes the disc choice difficult for determining distance, not to mention that the pin is plopped only 15 feet past the water.
The slope is what makes the course so fascinating in most cases, a mere consequence of the elevation.
Cons:
While many courses tend to challenge the right handed player by creating a lot of anhyzers, this course is far more righty friendly than most and was a bigger challenge to the left handed player.
That's not really a con, but I AM left handed!
Other Thoughts:
It's one of the best places because this old soybean farm--the older couple who owns the place spotted in the soybean field on the 5th hole and encouraged me to pick some to eat throughout my second round--is also a bed and breakfast. They now have a second course that is supposed to be far more challenging (called Big Brother).
I can't think of a better way to spend a weekend than to stay with your loved one and play disc golf.
