Pros:
Recreation Park features lots of holes that are fine for beginners but can still cause some challenges for advanced players. The front nine is fairly open, the back nine is fairly wooded, maintenance is excellent, and there are alternate tee pad options on several holes for players who want to stay away from the water, long grass, and woods. There are two practice baskets - one by each set of nine holes. Every teepad is concrete, including the alternate ones, and there's not very much mud here in my experience.
The wooded holes on the back nine are the highlight of this course. 10, 13, 14, and 15 are all super fun and have a few different options for how to play them. On many of these, it doesn't take a fantastic shot to get near the basket, but unless your drive is on point, you'll have no chance of a putt because of the guarded greens on basically the entire back nine. Upshots can also be difficult when you don't have a direct line to the basket. However, if you manage to play smart, you can methodically work your way down the fairway and pretty consistently avoid the thick woods.
A few holes on the front nine provide some interesting challenge as well, despite being relatively open and flat. Hole 2 is slightly uphill and plays near the pond, hole 6 has a low ceiling, and hole 8 is a blind shot over the pond. There's enough distance on nearly all of these holes for this course to not be labelled pitch-and-putt, yet less experienced players won't find their scores escalating quickly, and still have a chance for aggressive shots and conservative shots no matter how they throw.
Cons:
Because of the way the land is that the course is on, many holes end up not having much going for them. Many holes have one or two trees that get in the way, but when you really think about it, there's often not much that can block your disc (8, 11, possibly 9). Hole 12 has a row of tree directly in front of the tee that are really annoying, but still don't force a certain shot. It needs one of them to be removed - I don't care which one it is. Hole 1 is similar; it has two small trees in front of the tee, but you can still throw hyzers in any direction.
A number of holes massively favor a certain throwing style. Fortunately, it's not the same throwing style on every hole, but holes 9, 11, 17, and 18 all finish hard left, and hole 10, and to a lesser extent 13, finish hard right. On these holes, there's very little skill involved shot selection, and if the shot required isn't something you specialize in, you're toast.
Elevation change is pretty nonexistent on most holes. I quite like where it is in play, namely 2, 10, and 13, but some of the flatter holes could be a whole lot more spicy if they had some elevation change. Even holes that are just mediocre could be turned into holes that are really good (1, 11).
There's a whole lot else in this park than just Disc Golf. Sidewalks are the main thing that come into play on around half the holes, and some football and baseball fields are nearby as well. It's common to be waiting on the tee for pedestrians to move out of the way. If you're throwing across the path, it's not a big deal, but holes that basically play down the path are just dumb.
More importantly, more park infrastructure is coming in and is eating into the course. The tee of 4 has already been moved to avoid a new building, and hole 3 will need to be removed pretty soon due to some new lakeside stuff coming in. That construction has bled into hole 2 recently, leading to that basket getting destroyed. I'm not sure if it's been replaced yet.
Other Thoughts:
Once hole 3 is removed, the best fix to keep the course at 18 holes will be a hole after current hole 18 that plays to the practice basket. It'll be a boring hole and will cause 15 holes to be renumbered, but it'll keep the course a little safer. I'm not sure how the green of 2 will end up, but if that pin has to be moved as well, it'll be another knock on this course.
I'm not sure what the pars are on a few of the longer holes, but holes 12 and 15 can certainly be labelled as a par 4.
There's a rather long walk to get to hole 10, but if your putting is cold by the time you get there, you can go practice putting again. Or you can drive.
Unfortunately, I don't think this course is improving anytime soon, and if this park gets more and more people and buildings that don't have anything to do with Disc Golf, I fear the appropriate rating may be going down to 2.0. However, there's still some challenge to be had here, especially on the wooded holes away from the sidewalks, so enjoy this course while you can.
