Pros:
The layout of this course is a lovely, mostly par-3 challenge.
-Woods: Though some holes have unappealing park views, there are some holes out here with beautiful forestry. (3)-(4), (7)-(8), and (14)-(16) are a charming environment to play.
-Terrain: Along with these woods, there are plenty of other park features that make this a great choice for disc golf. Creeks come into play from (12)-(15) and gentle hills lend interest to most of the holes.
-Star Holes: A couple here could make a list of my favorite par-3s. (7) is a very challenging 400' left turn through the thick woods, (13) is straight and shortish but funnels down to a creek, (14) plays with a lake view on the left, trees on the right, and a right-to-left downslope, and (15) works downhill from the field into the woods with a creek-guarded green.
-Shot Shaping/Gameplay: The 14 holes I played here showed very good diversity and reasonable challenge. It's mostly par-3s, but there are varying levels of tree cover, fairway bends, and distance. There are thick woods technical challenges, a couple of pretty open drives, and some holes with a change of biome part way through. Other than (12)-(13), no two holes feel the same. In its heyday, I think Deer Lick would easily be a 3.0 and pushing 3.5.
Cons:
Badly in need of better care.
-Overgrowth: Dreadful in parts. (6), (9), and (10) are virtually unplayable, being mostly engulfed by weeds taller than me. A lot of the other holes could use underbrush cleared for both gameplay and comfort, and possibly a small tree or two removed on some of the woods holes.
-Altered Layout: At some point, a couple of the holes got moved. (UPDATE: Just figured out it was the "redesign" in 2016. Unfortunately, neither UDisc nor old course maps have been updated anywhere I have seen.) Using UDisc, I couldn't find (1) or the teepad for (2), so I started at (3). (3)-(9) were fine, and then I never found the teepad for (10) despite locating two baskets numbered (10). At this point, I discovered that hole (1) had been moved to make way for a retention pond, with the new tee near basket (10) and the basket closer towards basket (2). After playing this hole (never did find a tee for (2)), I backtracked to the baskets for (10) and located hole (11), which was also several hundred feet off from the UDisc layout. The rest of the course was as previously. Note that the course map here on DGCR begins at hole (12).
-Navigation: Even disregarding the undocumented layout alterations, there are some flow issues. After the first 9, remaining holes are bunched up. (10)-(11) are next to each other, but then it's a long and uncertain walk to find the hole (12), then another go-with-your-best-guess to find (15) far across the street from (14), and another non-obvious straight walk 400' from basket (17) to tee (18).
-Parking: Due to ongoing construction, there isn't parking very near hole (1). Your best bet would be to start at (11) or (12).
