Pros:
Nice little out of the way course on State Park property.
Camping on site, would be a decent place to camp and hang out, seems like there was a variety of hiking trails and "WIHA" (Walk in Hunting Area) to explore.
Variety. Each hole had a slightly different variety, from wide open, to doglegs, to some tight slightly technical shots, in general there was enough obstacles to keep it interesting.
Amenities. Bathrooms, camping, water, ample parking and a very creepy shelter thing (the showers were full of spiders and rusting metal, the basement had a "church" style fireplace room was kind of cool).
Ace/Birdie Opportunity. Every hole is reachable in one, mostly not gimmie birdies, but the opportunity is there.
Not Crowded. I don't foresee many people making the trek out here, I'd bet the course will be yours to play as many quick rounds on as you'd like.
Cons:
Navigation. Notice holes 6 and 7 when driving in, it's a bit of a walk from hole 5 to 6, I'm glad I vaguely remembered a basket on the drive in, hole 6 tee was just off the road as you walk out past the tunnel of trees. Hole 7 tee I never found, nor did I find hole 8 tee. The rest were rather intuitive, just look for the mostly grown over toe boards.
Location. I'm not sure what would bring anybody to Oberlin Kansas...
Short. Most holes were just over 200 feet, with the longest maybe approaching 300.
Other Thoughts:
A worthwhile stop if you're in the area, passing by I'd stop for a quick 9 hole round and maybe even camp out there. I wouldn't make it a destination or go too far out of my way for this one though.
