Pros:
To preface this review, the trees around the course have grown up and filled in A LOT on many of the holes since the course photos were taken so the course looks/plays much differently than it would appear. If I'd have realized this I'd have taken new photos while I was there, but alas I didn't. Into the review.
1) Despite the average hole length only being ~190ft, the layout is surprisingly good. Very good balance of straight, left and right shots. Being able to throw both forehand and backhand is important if you want to get into the circle on every hole consistently.
2) On the back of the first point, there is a fair bit of technicality here. Very narrow, but mostly fair, lanes on hole 4, 7, 8, and 9. Of these hole 4 is the most questionable. You have a ~10ft wide gap like 70-80ft out with a very low ceiling. After the gap it's a sharp dogleg left and the basket is about 60-70ft out. The only play is a LHFH/RHBH skip shot or maybe a right forehand roller. If the hole was any longer I'd say it's absurdly dumb, but with it being so short it's not as demanding as it looks on the tee. I got 2 birdies, a par, and a bogey in the 4 rounds I played before this review. Holes 7, 8 and 9 are the best part of the course. 10ft wide tunnels; 7 goes mostly straight, 8 doglegs right and slightly uphill, and 9 doglegs left and slightly downhill. All of them are very easy birdies if you hit the line, but you can very quickly find yourself in bogey-ville if you kick early. Hole 1 is just a mostly open straight shot but getting around/over the middle tree and keeping it in the circle can be tough, it's the only hole I didn't birdie in the 4 rounds I played. Hole 3 is also mostly open, but forces a lefty hyzer and has a couple grabby conifer trees that will stop you short of, or just inside, C2 if you push it a little long.
3) Innova Discatcher baskets. In great shape and catch like you'd expect.
4) On site port-a-potty is always a plus, especially on a course without and public bathrooms anywhere close. I didn't use it so I have no input on if it's emptied regularly/frequently or not.
Cons:
1) The tees leave a lot to be desired. They are all rutted out gravel. They're not so bad to make it dangerous; they are all plenty useable but definitely close to being risks for rolling ankles. Hole 1 is just in the middle of the gravel path, the rest of the tees have wooden frames around them.
2) The conifers are extremely overbearing in places. Holes 3 and 5 clearly were intended to have straight gaps, but they just don't exist any more due to the conifers growing into them. Then the wooded holes that are lined with the conifers make some of the worst jail you can imagine if you find yourself in them. I get it, don't throw there and it's not a problem, but everyone is going to be there eventually (especially with how narrow the woods holes are) and it is simply not fun to even get to your disc, much less try to throw out of it. I, mostly, got lucky but I could see people getting stuck in them for 2 or 3 strokes before getting out if they get some bad luck on a kick. Just a little bit of trimming on the open holes and a little bit of pruning of the dead branches close to the ground in the woods would basically remove this con.
3) Also on the topic of the rough, there are lots of stabby plants in the tall grass. This in itself is not an issue but some of the tall grass is very much within C1 of multiple baskets so keeping out of it can be very difficult. Wear long pants or just be prepared for your ankles/shins to get scraped up. Mowing a just 5-10 feet more around the baskets would go a long way to making it a more enjoyable experience play here.
4) The weak points of the design are holes 2, 5, and 6, though 6 is the best of these. Hole 2 is pretty unremarkably boring. Wide open, under 200 feet. Hole 5 looks like it used to be much better, but it's now basically a forced LHBH/RFHF spike hyzer as the middle gap is almost completely closed up due to the conifer trees. Hole 6 is a fun little hole, but again just short with almost no risks unless you pump it long and end up in conifer tree jail. Additionally, many holes have those large, grabby conifers very much inside C1. Hole 5 you can be 10 feet out and have nothing even close to a clean putt. That is by far the worst offender on the course, but a few other holes have similar frustrations. Again, just like con 2, a little bit of trimming and/or pruning would solve this issue completely.
5) Related to the layout, this course is very cramped. The baskets for hole 2 and 5 are inside each other's C1s, if not extremely close. Most of the tee pads are very close to other baskets and the only viable line to the basket on hole 3 requires you to throw right over hole 5s tee. I played on an 80 degree day in November and everything else around (disc golf or otherwise) was packed to the brim and only saw 3 other groups in the 1.5ish hours I was there. So, this course doesn't seem like it's ever too busy, but these issues could be problematic/dangerous if there was more than 3 or 4 groups on the course at once.
6) Pretty minor since the course seems to not be very busy, but parking is very limited. Street parking only and only on the same side of the road as the park. Do not park across the street or you may get a ticket.
Other Thoughts:
Overall, it's not a bad time but it needs a little bit of work. Very short but deceptively tricky, higher level players can go putter only and almost anyone could get through here without even a fairway driver. With a bit more length or some tree trimming/pruning as mentioned above I'd bump up the rating to a 2.0 as I'm very close to doing so as it but there's just not quite enough there for me. 9 down is certainly doable, even for someone well below 1000 rated, but you need to be on your game to get it as just a small mistake on the woods holes completely takes birdie out of play. For reference I'm about 915 rated and averaged -3 on my four rounds with some exceptionally terrible putting. I wouldn't recommend driving out of your way for it unless you are just looking for a place that won't be busy, but it's a super quick round (under 20 minutes if you walk fast) and I'd say it's worth a stop if you are nearby and have some time to kill. Though, I'd recommend Brekke Park just down the road, on the other side of Stillwater, over this course if you've never played either and only have time for one.
