Pros:
Legacy is a really popular course with lots going on in the other parts of the park. It has a mix of open and wooded holes, but even the open holes have some trees on them (usually). There's at least a little elevation on nearly every hole. Upkeep is pretty good, with grass in fairways kept short and small amounts of tall grass left between adjacent fairways.
There are 2-4 pins on every hole, and most of the longer ones are par 4. That being said, the par 4 pins are very easy compared to the par 3, to the point where even intermediate players have a chance at eagle every now and then. On only some of the par 4's is the first shot a placement shot, to try to give yourself a look for a 3; on the others, you're just trying to get as much distance off the tee as possible. I like having some pins labelled as par 4, though it is a little inconsistent how they are labelled.
There's a pretty decent mix of uphill and downhill holes, and no two holes feel identical. Hole 7 is unique because it's up-and-down, so having the right angle on the disc is difficult. Several other holes play slightly downhill, which is fun because it's easier to get some extra distance. Overall, the place isn't super hilly, but the hills were utilized pretty well.
There's a practice basket down the sidewalk from hole 1, and you can play hole 18 to that basket for an added challenge.
Hole 9 ends by the parking lot, so you can easily start on the back nine or quit after half the course. Overall this is a pretty easy course to navigate, and while the course map is a little outdated (only shows around half the pins that exist today), it'll be good enough and you probably won't need it anyway.
Cons:
A bunch of holes are just a little underwhelming. Several holes on the front nine, and especially holes 10 and 11, have wide open fairways but some annoying rough to get into. Several shots are also blind because of the shape of the hills, including the upshot to 3's long pin. While that can be an interesting challenge in and of itself, it's not all that fun to play.
Some of the rough can be punishing, though it has gotten better over the years. It's common to see groups looking for discs, especially on 1, 3, or 8. Given that a lot of beginners come here, clearing it up would make this course much better. And for some reason, discs seem to go into the rough more often than they should - unless you're an advanced player or above, be on the lookout.
New tee signs show all pins that are available, with distances and pars, but signs overall are absolute trash. Some labeling of par is pretty ridiculous; holes 3 middle, and 4 middle, and 8 short, and 14 long should all be par 3, and 6 long should be par 4. On the sign of 8 short, it shows a par 4 pin that was taken out and doesn't show the new par 3 pin. It's around 330 feet, not 410. The maps might as well not exist. Finally, the distances are super inaccurate, sometimes by as much as 50 feet.
A lot of the trees are pretty short, which means intermediate to advanced players can just throw over them. Other holes have trees placed almost right in front of the tee, depending on pin placement. It makes some holes pretty boring, while offering no line for beginners. The worst offenders here are holes 2, 6, and 16. However, they have grown significantly from when the pictures were taken (especially holes 2, 9, and 17). Some of these trees are rather thorny and are annoying to look for discs around, even sometimes in the middle of the fairway.
A sidewalk winds its way through the back nine. The course usually stays clear of it, but there are left routes on holes 1 and 13 that take you right over the path. Watch for people first.
Other Thoughts:
This place is windy constantly. It adds to the challenge, but for some reason, it feels like every hole is a headwind.
A couple of places, mainly around the tee of 1 and a few pins on the back nine, get soggy constantly. It's not bad enough to be a con, but if you're hearing some squishes at the start, don't turn around and leave.
Unfortunately, the city has had a hard time embracing Disc Golf. There's never any tournaments here (though there are sometimes leagues), and the local club has a hard time doing anything for the course. This is probably why it took so long to get new tee signs. At least the mowing is decent. There's also some land behind holes 3, 4, and 7 that's more wooded than the back nine and would make for some great holes. I think it's theoretically possible to get a championship level course here, but it's probably not going to happen anytime soon. I would like to see the practice basket moved closer to the parking lot and the existing practice basket pin be turned into a super long pin for hole 18.
This is a fun course, but there's really nothing to rave about. If you just want a casual round with some decent distance but without ultra-long holes, this is a good place to stop. But there's really nothing that stands out to make this course deserve a high rating. Maybe that's me getting bored after playing it over dozens times, and maybe a lot of the holes here don't offer significant challenge.
