Pros:
Mostly flat course, which has two distinct parts, built in a peninsula along a bend of the Iowa River. There are two tees and two basket positions on every hole and most of the alternate tees offer different lines, so you can play 36 different holes of golf here. There are rarely any other park users in the disc golf areas, except for an occasional dog walker.
Holes 2-10 and 12, require a variety of tight technical lines through thick established woods with some impressive old oak trees. Even though they are tough lines to hit in some cases, there are usually a couple of options on most holes. Holes 1, 11 and 13-18 are mostly open, windswept holes with low scrubby brush lining the fairways. There are several legitimate par 4 holes (1,5,6,10,11,13,18) although some become par 3s depending on the basket position. Holes 5 (blue tee) and 6 are excellent placement challenges, where even if you stay off the trees, it is tough to land the disc in position to have a clear line to the basket for a birdie 3. The course is fairly well-balanced between right-to-left and left-to-right, but this can vary a lot depending on basket positions. Big arms can reach quite a few of the longer open holes, so players without a 400ft drive need to score well in the woods to be competitive.
The overall design takes advantage of what little elevation change is available, but it is not much. There is a low bluff of about 15ft or so that divides upper and lower parts of the course, and most holes don't cross that bluff. But from the blue tees there are three fun drives (11, 12, 15) off the bluff with downhill elevation change, and one uphill approach onto the bluff (5).
Cons:
The land doesn't really allow much variety in terms of elevation change. Holes 11 and 13-16 are in a flood-prone area, and in some years it can become unplayable depending on how high the river is. And even if they are not flooded, the ground may be too soft for the mowing equipment so it can get rough. When the mowers do make it in there, they leave behind some nasty ruts, so you have to watch your step -- once the ground gets hard it is easy to turn an ankle if you're not paying attention. The woods holes 2-10 are notorious for stinging nettles if you get off the fairways. They can be brutal in the summer months. Flocks of geese hang out along the fairways of holes 13 long, 15 and 16 during the winter and it gets a little nasty.
