Pros:
A run-of-the-mill, but unobjectionable, open course.
The course basics are put together very well, and maintained. Concrete teepads are spray-painted with numbers, baskets are new Prodigys, and the grass-cutting and other maintenance was top-notch on my appearance. Staff was also friendly and helpful to get me started (since there isn't a course kiosk marking the first hole yet). The layout of the course is such that the flow is almost seamless, other than a long transition between (6) and (7). I'm guessing, based on the level of care that has been taken so far, that solid signage with hole maps is coming. Inside the rec center are water fountains and bathrooms.
The land is very flat and very open. Tree coverage is limited to a max of 8-10 on any hole, with some having zero. Distances aren't labeled yet, but I would guess that they are all between 225' and 400', except for the par-4 (18). As such, this is a good course for long-throwing rec-level players, as there isn't a lot of shaping to contend with but the distances are too long for true beginners to have a lot of fun.
Speaking of shaping, most of the holes out here are straight. The holes with trees are typically designed to be played through and under, and only a couple of holes will require turning shots to avoid dead-ahead foliage. The (13)-(15) range does a good job of forcing you to pick a line and/or navigate guardian trees, (10)-(11) have a street to the right to heed, and (17)-(18) are probably the coolest part, as they play straight along a river. Thus, there is slight interest throughout Trion, but it's quite open and forgiving.
Cons:
The biggest issue with Trion is that it's on a boring piece of land. Tree coverage is sparse at its densest, and accordingly there is extremely little shaping to be done. It's a utility course, but has nothing to offer someone who has played more than 10 courses already. Further, I'm sure the exposure is brutal during hot and sunny summer days.
The course is new and doesn't yet have all the amenities you'd want. Signs have yet to arrive, and there isn't a course kiosk with map either.
There are some safety issues out here. (3), (6), and (13)-(16) all play along a walking path, with (10)-(11) alongside a not-unbusy road with private property on the other side.
Disc loss is a major risk on (17)-(18). These are as boring as any holes out here except for the fact that a river borders the fairways on the right, which is very nerve-wracking.
To be nitpicky, the walk separating the loop (7)-(12) from the rest of the course is a little annoying, but not really an issue.
Other Thoughts:
Trion is at the lower end of Typical for me. There are just enough well-placed trees and river holes to save it from a lower rating, but this isn't somewhere I really plan to return to. It fills a space in North Georgia without very many courses in an adequate but hardly thrilling way. All that said, I am impressed by the execution of the course, and I hope it continues to get a lot of attention so it develops a solid local scene. To any Trion city staff reading this, congratulations on doing a very nice job with this course - keep it up!
-Signage: Please PM me if the park adds tee signs so I can update my review. I would expect this to happen before long.
