Pros:
The course has some major elevation, but you are not just throwing up and down a hill, but rather onto other "hills within hills," where a hump in the fairway may slope in a different direction than the fairway itself. For most putts you will be putting on a slope, creating the kind of risk/reward decisions from 30 feet out that make courses interesting. Each hole has at least four basket positions, so I doubt you could get too tired of the course. The signs, some of the best I've seen, graphically depict the locations of the various positions. There are no real filler holes here, and many holes make you consider the trees you are throwing under, in addition to the elevation. Your second shot will be key here. If you can land your disc flat within 20 feet of the basket, you're fine. Otherwise, watch your disc burn rubber downhill!
Cons:
On a couple holes the basket was not visible from the tee, and the signs were not helpful in figuring out where the basket was. Course flow here is okay, but you'll probably need a map your first time. Several times I couldn't figure out where I was supposed to go next, and that fact that two temporary baskets are in use didn't help. One of those temporary tees has you throwing a blind shot right over a park road, and you can't see if traffic is coming up the other side of the hill. Only one hole here was kind of boring (maybe #14? It was just a straight shot to a basket in the middle of the fairway with no trees or elevation factoring in).
Otherwise, there aren't many cons, just slight things that would make it a 5-star course. I don't believe there were alternate tees, so I'm not sure how challenging this course is for a very good player. There are no technical wooded holes or water holes (which obviously might not be possible here), so while each hole is fun, they're all of the general type "semi-open and hilly." I'm stretching to come up with things that could make this course better, but really, it's that good.
Other Thoughts:
I can't imagine this piece of land being used for anything else. You couldn't really play baseball here, it wouldn't be ideal for a picnic, and a game of horseshoes would be comical on these hills. It was a park made for disc golf. This is a model for course creation in parks, and if you're in the Midwest, you owe it to yourself to play here. I will happily make the drive from Omaha again.
