I saw some posts earlier in this thread dogging on this course, but it's actually quite beastly. The OB is everywhere, but also very fair. Go back and watch the final round and playoff of 2014 World's (it's only the greatest DG battle ever - so much drama and so many big putts).
I almost took a picture while I was playing there yesterday to actually show how tall and aggressive the rough is right now. It's well over 6' tall in places where you're actually having to throw accurately to avoid getting into it. It's probably one of the biggest factors of this course, which doesn't really offer a wide variety of ways to attack the basket, but will mentally wear you down with how prominent the OB is. For many of the holes, you simply can't even see the next hole you're playing or how little room you have for error because the rough is so tall, aggressive, and widespread.
It's an extremely intimidating course that, as I said, will challenge your mental game significantly, especially as you get deeper into your round. One really has to look no further than seeing the mental errors and challenges that the top players in the world faced on holes 15, 16, 17, and 18.
While it doesn't necessarily look like a 'pretty' course on tape, it's really got it all in terms of challenging disc golf... low ceiling play, some narrow and treacherous fairways, blind shots, subtle elevation, big distance, etc.. To play it well you need to be able to throw all your shots with distance, accuracy, and be able to mentally recover if, errr... WHEN you throw OB.
