Pros:
Visually this course is well built and beautiful. The tee pads are huge and widen toward the top. This is nice because quite a few holes are over 300ft and the tee pads provide ample room for a run up. The baskets are high quality as well. The course is mowed and has an open layout. Many of the trees on the course are fairly new and the course will improve as the trees get bigger. For instance, hole number four will eventually require an accurate drive through a dozen trees, but currently the trees are still short enough to play a disc over the top of them. The course is not usually very busy with other disc golfers, although many of the holes pass alongside of pedestrian sidewalks and there does tend to be a lot of other people using the park. Overall, the course flows nicely in a figure eight around and between the lakes.
Cons:
There were a minimum of 700 geese in this park when we began to play our round. The majority of them flew away at the same time and basically blackened the sky. I would normally consider wildlife a benefit of a course, but this was out of control. There is not a single square foot of the park that wasn't covered in goose poop. The lakes, as a result, are absolutely disgusting. Walking into the lakes to retrieve a disc is literally walking into dissolved goose excrement.
This course is straight forward and does not require many tough shots. Unfortunately, the few demanding shots it does have are over the lakes, so many players will take safe shots instead of trying their hand at clearing the water. If you do go for the basket on number two, the opposite bank is farther away than it looks so I recommend trying to overthrow the basket.
On previous visits to this course, I have found the grass soggy and over watered and I have also arrived at this course to find it completely flooded. The park is well maintained by normal standards, but park maintenance has some unique animal and drainage problems with this park that they need to address.
Other Thoughts:
There are not any other courses east of downtown Denver and Exposition Park becomes the default when I am in that area of the city. It is a fun course to play, but be sure to wash your hands and your discs when you finish.
