Pros:
The Wilmonster is a long course, and gives novice and open players plenty of length to air out big shots. In addition, the course does have a technical aspect that requires plenty of shots including forehand, tomahawks, pancakes, rollers, and of course monster backhands. There is never any traffic on this course unless a tournament is being played, and even then, you don't have to wait long. This is my home course, I live 2 miles away, and I play at least 2 times a week, I never run in to crowds or knee deep grass like some of the other reviewers have mentioned on here. The highest the grass has ever been, and I play this course all the time, was up to my calves in some spots. The park maintenence does a fine job of mowing, and not disturbing the baskets etc. I have even seen them mow around the basket even lower to give it a true green feel to the hole.
Cons:
Weak armed reviewers bashing a great course, and lying about it's upkeep. Don't you like to be challenged? If not, stay at your pitch and putt course. The only negative review that I will agree with is that the Wilmont does take time to drain after a lot of rain, but that is why god made aqua socks and waterproof boots!
Other Thoughts:
I actually think this is a great course for every disc golf player, because you get such a variety of shots forced upon you, that you have to practice them to be successful here. I have been playing this beautiful game for 20 years, and would recommend the Wilmont to anyone looking to learn how to play, or to increase their abilities!
