Pros:
Plains is an interesting, if flat, nine-holer that includes some good lower-level gameplay challenge.
-Amenities: Not a whole lot. However, wooden tee boxes have numbers and occasional distances, and the baskets are good.
-Terrain: Very flat, but Plains does a decent job of mixing open, closed, and in between. It's predominantly wooded, but (1)-(4) give you some open shots and breathing room to warm up before hitting the tight fairways.
-Shot Shaping/Gameplay: It's a par-27 course, but Plains makes good use of the available space. There's slight variety of distance from about 200' to 300', but the variety of shapes is especially notable. (1) is a moderately wooded "choose your own route hole", (2) is wide open, (3)-(4) are open shots leading to pocket baskets in the woods, and the rest are heavily wooded technical shots. Birdies will require some finesse and lots of commitment in the woods. Speaking of, I enjoyed the variety in the woods. Some were variations of straight at it, and there was one left and one right bend. I was especially thrilled with holes (1)-(4), which were fair and fun--see more below about the second half.
Cons:
The old trope of too many trees, and some infrastructure issues.
-Tightness: Hole (5) was laughable. Perhaps with enough tries you could throw a trick shot that went down this winding walking path of a fairway. (6) and (9) were highly questionable as well, requiring either two-foot wide precision for much of the fairway or luck. I had hoped to give Plains a 2.5 or 3.0, but these holes made that impossible, because they didn't give you a fair chance to throw a believable line.
-Overgrowth: Hole (8) is essentially unplayable due to woeful overgrowth. Some of the other holes are pretty prickly close to the greens too, especially (3) and (7).
-Drainage: Some severe issues when I visited. (1)-(4) were all very marshy, with the tee for (2) so muddy and flooded that it was dangerous to throw from. After rain or snow, it might be better dubbed Floodplains Park.
-Scope: Even in pristine condition I doubt if Plains could rise above Typical. It's a lot of nice 200-300' holes on so-so terrain, which just isn't the most fantastic possible disc golf out there.
-Navigation: With no tee maps or next tee cues, there were a couple of times that my group got turned around. Fairways (3)-(4) and (8)-(9) cross, which is the chief confusion. I would come armed with the DGCR map and/or UDisc.
Other Thoughts:
For a recreational to lower intermediate layout, Plains Park began remarkably good. The holes all feel different and require slightly different challenges each time. However, the woods section needs some slightly more generous fairways and upkeep, in addition to a series of other minorly annoying issues. Overall, I definitely enjoyed playing here, but its utility will be pretty limited. I think it's Reasonable, but a Typical course would avoid the issues of throwing line better.
