Pros:
This course is built in within a bend in the Big Sioux River, and brings the river into play on a number of holes.
Good variety of hole lengths from 175' out to 575', with most being in the 200' - 400' range.
About half of the holes are completely in the woods, with the other half being quite a bit more open. Even the wooded holes are not really tunnels, as the trees are large and spread out.
Seven of the holes play alongside or toward the river, and on each of those holes there is a real potential to lose a disc. The river is wide and murky with steep banks, so you'll probably lose a disc that gets out there. Hole 5 is a great one at 555', curving alongside the river.
A single concrete teepads for each hole. Flat with perfect texture.
Two pin positions for each hole. When I played they were pretty evenly mixed between the "A" and "B" position. Baskets were all in good shape, though they are tough to pick out of the shadows on some of the wooded holes. Hole 4 has a hanging basket which is interesting, but at about the same height as a regular basket so it doesn't add much.
A bulletin board at the parking area has scorecards and a map. You'll need the map to navigate so grab one.
Cons:
Tee signs were missing on about half of the holes, and even the posts were gone on a few.
A walking path runs throughout the course so there is potential conflict with other park users. Check the paths before you drive. There were also other users in the large field that Holes 16, 17 and 18 occupy.
The three finishing holes were just big drives across a grassy field. Not as interesting as the rest of the course.
Other Thoughts:
We camped at this park for three nights in April and pretty much had it to ourselves. It is great that South Dakota has included this course in one of their parks.
