Aesthetic - Very nice, park setting, rivers, wooded, rolling hills. Not a big fan of the vandalism on the signs, but this is an open free park.
Challenge - Yes, this definitely has challenge. I consider myself more rookie and had a pretty good first round, so maybe not too challenging, but awesome long runs, water wasn't really water hazards like a lake or pond to lose a disc in. I liked that the course was planned, and if you found your line, you can play it, unlike some courses with random trees everywhere, that is challenge.
TeePads/Baskets- Teepads concrete, 2 per most holes, baskets were great, kinda funny on the low lying areas where you can tell they probably stood taller but now the flooding of the area made them only about 6 inches off the ground, but they are fine.
Signage - Reasonable amount of signs for a complex course to navigate for first timers like me. If you use just the signs and print no maps you will probably get a bit lost, but will eventually find your hole, but you'll wander a bit that's for sure. Graffiti on some of the nicer signs spoils the mood of this woody area. Ssome signs have name of hole, #, distance, picture of hole, everything, sometimes there are markers at basket telling where to go next.
Variety - In Michigan, there isn't much more you can ask for, except for less mud (or more water holes if you're into that sorta thing). Mombo long run with few trees to get that long throw, tight technical shots, uphill long, downhill short, forehand, backhand, S shots. It's a good course. Somebody really thought about this course, the stood at each of the pads, and said tree here and here, not here, let them have a clear line here and there. I like the less randomness. Well planned.
Fun - Depends on who you are. Don't bring your non-die-hard spouse to this one. Not because of the challenge, because of the challenge and the wet/slippery/mud. But shoot even when she headed back to the car, I still had a blast and kept going, it was great... but it wasn't as good as if she stayed and played, always better to share.
Locatability - Finding the park, parking, no problem. There are lots of maps,
Maintained/Bugs - I went at end of March early April. Grass had just turned back to green (from dried out winter), not a bug in the air. Not sure if the bugs get bad later in the year though. I've read about downed trees in other reviews, but comparatively speaking to other wooded courses, and yes there are a lot down here, but for the most part, they weren't in the way at all. At this point in year, I thought maintenance was great, almost no leaves, short grass, so none of that super nasty thick grass off the fairway like some courses. Only thing, it gets wet.
