Pros:
A Course Near West Nashville: Kingston Springs is a bit west of Nashville, but if you live on the west side of town, this will be one of the closest courses to you. And unlike Trace Creek in Pasquo, this one is worth stopping at.
Two teepads: There are two concrete teepads per hole, and most holes have them about 100' apart. The longer teepad isn't "championship" level like the name implies, but it still gives a good opportunity to make this an 18-hole course by playing both sets of teepads.
Beginner-Friendly: From the recreational pads, this course is great for novice/recreational players. The longer pads are probably more intermediate level. Pro players will not find a big challenge here.
Nice Amenities: Besides the teepads, the holes have accurate signs. The baskets are standard innovas with the yellow band, but since they're still quite new they catch well. ***UPDATE: Unfortunately, the Harpeth River had a bad flood this spring and muddied up a lot of these signs, since most of the course was underwater. They're still somewhat-legible, but you probably want a backup copy ready if navigation/distances are a concern.
Large Field for Fieldwork: Ultimately, this might be the best part of the course for me. Adjacent to the parking lot, there is a flat, well-kept field about 300 yards long and 100 yards wide surrounded by a walking path. When I was there, no one was using the field, so I used it for some fieldwork. Once summer turns into fall (see below for a con), I will probably use this field even more since this is one of the only places in Nashville to get fieldwork in at an actual course.
Cons:
General Lack of Shade: Most of these layouts are fairly open with either a guardian tree or a "guardian dogleg" into a band of trees. As a result, there isn't much shade on the course, and it can get muggy as a result of being near the Harpeth River.
General Lack of Trees: There are no true wooded holes here. The designers tried to incorporate a stretch of woods into the course as often as possible, and most holes either dogleg into a pocket of the woods or run adjacent to them. Besides the drive on 6 though, there is no true tunnel shot.
Rough: When I was there, the long grass adjacent to the fairways was about 1' tall and fairly thin. If the grass gets taller/thicker, I could see it being an issue finding discs. ***UPDATE: they do the awful "cut a thin strip of grass and leave the rest tall" method of park maintenance here. Ultimately, the fairways are generous (maybe 50' wide), but for a beginner course there could still be a lot of disc-finding in the weeds.
***UPDATE: General Lack of Interesting Play: After making several trips here, the course gets boring quick. It is still nice for a quick round and my wife loves playing here cause it's easier than most courses, but most people above beginner-level will get bored fast. The only true "technical" throw required is on Hole 6, while the rest are either straight shots or relatively painless doglegs.
Other Thoughts:
I was pleasantly surprised by this course, especially after my experience with Trace Creek the week prior. There are a trio of 9-hole courses near West Nashville (this, Trace Creek, and John C. Poole), and ultimately I think this one is most worth playing. It is fun for beginners looking for a course to match their skill level, and keeps that fun factor for intermediate players looking to either score well or hammer some ace runs. Lastly, the giant field for fieldwork is the real selling point for me, and ultimately that will keep me coming back every so often.
***UPDATE: I still think most of what I said last year above is true, as it is a better 9-hole course than most. It does not provide much in terms of technical practice, but if you want to either improve distance or accuracy in the 250'-350' range, this course is great for that.
