Pros:
Disclaimer -- I played this course during the Standing Rocks Open tournament, and I am not sure how different the regular layout is, but I had the impression the tourney layout has a handful of temporary holes. My review pertains to the tourney layout only.
There are two parts of the course, an older shorter course, and a longer course with a few newer holes. Both are built on very hilly, wooded, and rocky terrain that is well-suited to challenging disc golf. However, both courses are mostly par 3 golf.
On the older course, almost every hole is a deuce run. Still it is challenging because of the technical lines through the woods, on most holes there is a good chance you'll end up scrambling for par after a tree kick. Even though some players might end up throwing a lot of midranges off the teepad, there are a lot of different shots needed, because there's a good mix of uphill and downhill, left/right/straight fairways. But the max distance drivers won't get much use on this course. There is one big downhill throw about 600ft down a ski hill (I think this was a temp hole) and the day I was here Will Shusterick was throwing putters at it. I threw driver and didn't make it. :-|
The newer course is a tougher challenge, several of the holes required more thoughtful disc choice and line shaping. There were also a few holes that had wider fairways where you could let 'er rip, kind of nice after playing the shorter old part of the course.
I took advantage of the camping at Lake Emily campground which was a pretty large campground. I didn't see the whole thing but the part I camped in was built into a sweet pine grove, it was nice and I would recommend it.
The whole area is beautiful and would be fun to hike around in, even without throwing plastic, so if natural beauty is important in choosing your disc golf courses, this one gets a bonus for that.
Cons:
The older part of the course seems to have been designed in a different era of disc technology, and needs an updated redesign to fully take advantage of the beautiful terrain. Even if it means the number of holes is fewer, I think the course could be improved by a complete redesign to include several legitimate par 4 and par 5 holes.
There are no water hazards, and OB looks like it would rarely be a factor. Penalties for going in the rough were not all that bad when I was there, but might be worse during mid-summer.
Other Thoughts:
All in all, I would say this is a great course for a relaxing day of golf suitable for lots of different skill levels, and I would definitely stop there again and have fun. But is not the supreme challenge that would warrant giving it a 4 rating or higher.
