Pros:
There are 18 nice, newer Chainstar baskets scattered about the Horizon Camp grounds, with a cadre of players who generally follow the pattern of the map posted here on DGCR (hat tip to ajbova!) to make a fun, challenging course for the Recreational to Intermediate player. Though there are no tee signs or set tee locations, this review pertains to the use of this map.
With rolling terrain, light to moderate foliage to define lines, and some really pretty infrastructure (including a pond and a little covered bridge walkway), the campus and the course are a great way to spend an hour or two. Holes range from about 170 to about 370 feet in length, include shaped lines in both directions, allow for longer arms to air out a couple, and for technical experts to play into some tight greens. For instance, hole 4 plays along the side of a large sports field, but is followed by two holes that actually play into some moderately treed woods lanes, where you do NOT want to go left into a rather deep ravine. Hole 10 features a basket position only a few feet from a 45 degree slope down to the pond on your left. There are even a couple of places where paved paths and driveways could be declared OB to force more conservative play. Even the short, downhill hole 17 could declare 'over the path' as an island green mando off the tee.
[edit after chatting with Brett Goodrich 5/29/16} Although the course has been technically listed as 'private', they don't mind at all (and actually would be thrilled to have you) if you play there on off days (reportedly after 6pm and on weekends, but please don't play if they have other activities underway). I saw four groups on the course on the weekend day I visited.
Cons:
The lack of tees and signage mean you can't really compare scores or hold events (unless the TD is willing to mark with flags), but it does reduce erosion issues on the tees that must throw from the grass. Hole 1 (from the parking lot corner) is assumed to be a mando left to right around the basketball court fence, but throws over (around) a volleyball net. If not a mando, there might be folks who will try to spike hyzer over the basketball pavement (unwise). Transitions are a little awkward on hole 9, where you basically 'shelter' your tee shot from hole 8 by stepping beside the cabin to throw, and you still have a strong chance of hitting the windows of the building across the way. Then you have to walk around that building to throw hole 10. Hole 16 has you throwing over (around) a small parking area.
Other Thoughts:
I paced all the holes as marked on the (DGCR) map, and gave rough approximations of distances, but that kind of accuracy is very limited. My rating had to be held down because of the lack of defined tees. This would definitely be a 3.5 or better if they modified one or two places for safety and flow, and installed permanent tees and signage.
Reviewer Background as of this writing: played 264 courses and written 248 reviews, with skills hovering around a 900 rating, I started playing at 50 and am now 55. I don't throw far (300 footers feel like success), but am addicted to DG, and have played with folks ranging from age 7 to 87, so I try to write reviews helpful to all.
