Pros:
-good new Innova baskets; hole numbers on baskets are correct
-tees overall are concrete and in good shape
-course flow is quite good without overlapping fairways
-much improved hole design with good use of elevation and trees; more improvements still in the works
-interaction with park/path has evolved over the years, but course designers have done a good job using mandos to minimize chance of throwing on other park users (e.g. holes 1, 16)
-new splash pad for the kids by parking area and first hole, and the walking path is in good shape
Favorites:
2 - throw along creek w/ pesky branches to substantially elevated basket
3 - nice "up the gut" line as well as a low RHBH hyzer line; nice wooded hole
4 - throwing to a gap about 150 to 200' away with a nice descent to the basket
10 - straight/turnover/forehand with a basket placement among some thin but plenteous trees
13 - fun basket placement next to the creek with plenty of mature trees crowding the sky and low lines; nice risk/reward hole
Cons:
-Several holes throw over or near the path, with the worst being 14 and 17. I love both holes, but make sure the coast is clear.
-a couple tee boxes are small (3) or narrow (5)
-Navigation can get hairy your first time though basket to tee navigation is usually obvious. 3's tee is probably the trickiest, as it's not visible from 2's basket. 4 can be tough because there's nothing sticking out of the ground. 6's and 8's tees are close together but they are labeled so it's straightforward. 18's tee requires a short walk that isn't obvious. Both maps currently on DGCR are pretty good. I think map II, uploaded in 2016, is a little easier to use.
-some of the tees are numbered, but most are not; some are just concrete pads without anything sticking out of the ground (especially 4 and 5), and one is currently missing a tee (13) though there's a bench marking the location and you can throw from the path
-though in a city park, I've heard there are water moccasins and had my worst disc golf tick bite here
Other Thoughts:
This was one of a few courses I played back in 2005 when I first started playing. I saw it go from a decent 18 hole course to more like 12 because of a new apartment complex. It remained in a relatively poor state until 2015, when damaged badly by flooding. The local disc golf club took the opportunity to fix it up using plenty of volunteer hours and some funds from a city project called "Norman Forward." It's now a very respectable 18 hole course that utilizes a creek to great effect on many holes. The new baskets are a big plus, and the regular maintenance and trash pickup are obvious.
The park continues to grow, and this is one park I've begun to bring my whole family to while I play. Last visit, my son enjoyed the new splash pad and then got some quality stroller time. It's a beautiful park, making for good time outdoors in Norman. Several holes have had to evolve due to the path or splash pad (e.g. mandos on 1 and 16, with 16's first tree uncomfortably close to the tee box), but the changes are for the best. I appreciate that Sooner Disc Golf is collaborating with Norman's parks, as this ensures that holes are neither blatantly unsafe nor terribly boring.
At my last outing, I met one of the Sooner Disc Golf guys who does tons of work on all the Norman courses. Thanks to him and others, Griffin, Lions, and Colonial Estates are really at the top of their game. Emptying trash cans the city guys often miss, weed-eating next to the creek, and putting in benches are just some of the things he's been doing. At least 3 holes have new pin locations being considered, and improvements like tee signs are supposedly in the works.
Overall, hole quality is good. Elevation is used well on multiple holes, as are the creek and trees. It's not the most challenging course in the area, but the creek provides plenty of hazard while the trees prevent it from feeling too open. 18 is kind of a "filler" hole, but it's still decent. Wind is always a factor, meaning you'll have a decent number of headwind/tailwind shots, with relatively fewer crosswinds.
My rating is 3.0 for "good." I've updated it to match many other courses and reviews since I last played. The recent improvements and the continual TLC are noted and appreciated. Thanks to Sooner Disc Golf and Norman Forward for the improvements! Now you've got me spoiled, so I'm expecting even more!
