Pros:
Disc golf on a ball golf course, executed to a high level.
-Upkeep: The course is pristine, as you'd kind of expect on a ball golf course. Some of the rough on the technical holes (like (2), (17), and (18)) is a bit thick, but the fairways are clear and it's still manageable. Notable exception to this pro is the teepads--see cons.
-Terrain: The only other golf course I've disced on was ultra-boring, but Nashboro impressed me with its diversity of terrain. There are some big hills, a nice creek used several times, and a good mix of wooded and even thick forest holes throw in with the open shots. The number of holes where you're driving straight down a golf fairway is less than a handful (and all of those have pockets at the end).
-Challenge and Length: The back tees come in at over 8000 feet, making this a substantial track. However, it isn't a one-dimensional challenge, and that length has to be played smartly. Adding to the challenge are the Strikezone targets, which make putting substantially harder. I'd peg it as upper intermediate or advanced-level difficulty from the longs.
-Shot Shaping/Gameplay: A diverse challenge that I found to be a total blast. Five par-4s and two par-5s are mostly true multi-shot holes. The mix is of technical, open, and in-between, but I didn't find there to be any totally boring holes. The technical holes, though short (or short portions of multi-shot holes), will have all but needle-threaders quaking, but standing a chance. The open holes do a fantastic job of providing interesting greens or other challenges. I love (3) and (8), which play downhill over beautiful creeks to challenging greens. Multi-shot open holes let you go big, but a smart drive will make the approaches into treelines far easier. Two examples are (1), a downhill drive fading right into a tight tunnel, and (9), a par-5 starting with a right-turning drive that then plays down a fairway and has a couple of tree-defined options to go over the creek to a windy green. There are a few holes in between these two sides that play through considerable trees but have more line-choosing flexibility in an older style a la Brahan or Henry Horton.
-Flow: The flow actually makes a lot of sense, despite there being long transitions. The rule is either go to the next tee you see or follow the cart path until you see another tee. Some signs also get you pointed in the right direction.
-Multi-Tees: I feel obliged to mention that there are two tees on many holes. However, I don't believe the short tees have pads and are just natural.
-Second Course: Fun little par-36 course is also on site.
Cons:
Quite a few minor issues, but nothing that detracts too much.
-Signage: Signage only holds a QR code that you have to scan to view the digital sign. This is really quite bothersome, and I wish they could design and install some really nice signs to match the quality of gameplay out here. Unfortunately, a groundskeeper advised me that the designer, not the country club, paid for all the baskets out here, so the odds of the club putting up money for nice tee signs seems pretty low.
-Tees: The tees don't get a lot of love. They are turf in varying conditions, but some of them are being overtaken by mud. On the bright side, there were several noticeably new turf pads out here, so perhaps they are slowly replacing the worst ones.
-Golf Course: A couple of things go with this. First, you have to yield to golfers, which was only an issue for me once on the two courses. Second, there is a greens fee. At $4 for both courses all day, it was incredibly worth it. Third, there are some pretty long walks between holes (more designed with carts in mind). Of course, on a dry day you can just pay $6 and get the cart included. Fourth, tee times are limited to Monday-Thursday. Fifth, I imagine exposure is an issue during the summer months, but that's a pretty common problem on non-technical courses in this area.
-Beginner-Friendly: It's not. Don't bring a beginner. The long holes will be too long, and the short holes will be too tight. Not to mention the baskets are too small.
Other Thoughts:
From reading reviews, I thought Nashboro was likely another over-hyped bomber course that would be rather dismal, like the other golf course I've played. I'm exceedingly glad to say that it was not, and it is just barely my new favorite course in Nashville. It provides a really good balance to the technical gameplay common at the other top courses in the area (Cedar Hill, Seven Oaks, Cane Ridge), but it still has some technical elements and some plain fun shots, especially downhill shots over creeks. I wholly recommend checking out the course if in the area on weekdays.
-Strikezone Targets: The baskets are Prodigy Strikezones, which are ultra-thin targets. I'm not calling this a pro or a con because I do not want to get embroiled in the "should the basket be smaller?" discussion. However, it is very important to note this and consider whether you will enjoy it or hate your day because of it.
