Pros:
Challenge - tight technical fairways through thick woods with usually one obvious opening force you to hit the line or suffer the consequences - the rough is thick...
Variety - up, down, left, right, and straight fairways are all here.
Beautiful teepads - long, wide, and made of beautiful brick
Sufficient teesigns with par and length, and general fairway direction
Very picturesque - as others have stated, the course plays on old foundations of Negaunee that have since been abandoned. It's really cool to see the old sidewalks, signs, and whatnot as you play through a forested dg course. One hole has an old concrete basement pit as OB right before the basket, which is both cool looking and a neat hazard. Another hole has the basket on the bottom of a run of flat concrete foundations that continually steps it's way down the hill.
Plenty of ace runs, as well as a few placement par 4's and challenging long par 3's.
Nice new Chainstar baskets.
Practice basket on site.
Cons:
Difficult to find - the address listed doesn't really have a street sign, the street seems to be one of the old abandoned ones, and the course is off in the woods across a bike trail with just a small gap in the trees where you can see the welcome board for a split second if you are keeping a sharp eye for it. Very easy to drive by and not even know.
Flow - the front 9 and back 9 feel like completely different courses - the front 9 is almost all short ace runs in the 150-220' range, and the back 9 features mostly all longer par 3's and even some short par 4's. Would've felt less awkward overall if they mixed in some longer holes on the front and some more short holes on the back.
Teesigns - they're nice and provide length and par info, but a general direction arrow with no actual trees or obstacles on it for reference can make a couple holes confusing. They're good signs, but that vagueness can also make this a con.
A couple of the teepads are slanted a tad.
Navigation can be difficult in between a few holes (specifically between 17 and 18). I would advise taking a picture of the map on the welcome board.
Fresh, thick, and just not worn in yet - there are plenty of branches, bushes and leaves that could be taken out still to provide cleaner airways on some holes, and you can just tell the course is super new and a bit rough around the edges. I'm sure with time and local club work that it will get better, and it would probably be enough for me to possibly come back here and raise the rating a half disc.
Not many, if any garbage cans or benches.
Other Thoughts:
Good to see another solid course put in in the area. This so far seems to be the tightest course out of the current three in the area, but it's hard to tell for sure because Marquette's courses are known (at least in my mind) for having some of the tightest tree lined fairways around. Definitely a great place to challenge you but also give you a fair chance at scoring low. Quite a unique setting with historic vibes, and an all around good time.
