Pros:
UMD is a very beginner friendly course. It's where people in the Duluth area should go and play first if they want to get their feet wet with disc golf. It provides 9 holes that have some good mixture, yet don't prove too difficult for those who have little experience.
The course itself is a simple 9 hole, not too many obstacles, a few sections of OB, a giant sculpture to navigate around (or through if you want to impress your friends), and a quick and easy playthrough. By yourself you can likely finish in 20-30 minutes.
The course has a good mix of basket lengths too. The shortest being 120ft and longest being 258ft. Aces aren't uncommon here, so it is another mark for impressing your friends.
Cons:
It's almost too easy of a course. Those who play often, or have played other courses in the area will find little challenge here. The few obstacles aren't all that punishing and it provides little risk/reward shots. There are little shot variety, almost every hole can be completed by shooting straight down the middle of the fairway.
They also removed a tree near the tee on #3. It makes the hole much much easier than before. Your only threat is the two trees on the right which are easily avoidable.
Depending on the time of year and/or day it may be very busy and you can be waiting behind a group, especially during the nicer fall and spring days with students wanting to get outside some more.
The course layout isn't anything to write home about. It does not loop back around and it is confusing for people who have never played or seen the course to get a grasp on the layout.
Other Thoughts:
It's not a bad course by any stretch. It's well maintained, the baskets and teepads are in great shape, and is in a popular part of town. It is simply a beginners course and anyone who has more than a year or two of experience will simply have to lower their expectations on this.
