+Rolling hills park is a nice place that is maintained by the city of Carroll. It has the Sauk River Rail Trail running through it. There is a shelter with bathrooms and a few tennis courts. Likely more parking than you would ever need.
+Concrete tees (see cons)
+Baskets in fine shape.
+Good for beginners and new players.
+Many ace runs possible.
+Navigation is easy here.
+Shouldn't lose a disc. There's some rough on the East edge of the park near the river but it should be pretty avoidable.
+Decent variety of distance. 6 ace runs and 3 longer holes.

-The number one con is the big white PVC pole marking each tee. They are stuck right in the back of each tee box. They are in the way of a run up on already short pads. Good thing the holes are pretty short.
-Be careful of the bike path on the back part of the course (6-9)
-Despite the name of the park, it's actually pretty flat. There's a few light hills but I expected more.
-Not enough trees to make things very interesting. It's pretty open.
-No signage. Even on basic courses, it's nice to have more info on the hole without opening a phone.

+The PVC poles cost this course at least .5 disc rating. This park isn't terrible and has potential to get to 2.5 with a few updates.
+Good warm up for Swan Lake which is just a few miles away.
+There is a river on the East side of the course but it is small and just far enough away that it shouldn't affect the round at all.
