Kline's Run is essentially a very, very big hill, with large hardwoods scattered throughout, a creek along the northside, and views of the Susquehanna. The disc golf course plays up (often), down/atop/across (somewhat), and along the creek/roads (sometimes). Elevation changes are the primary challenge, as the trees are most often fairly well spaced, with only a few denser pockets, and hole lengths (mostly) are not oppressive.
My (RHBH, ~315' max, ~285' typical) perspective of the holes:
#1 Short, steep uphill, open, a few trees late
#2 Short, flat, single tree at 2/3rds point, sharp drop-off right/behind basket
#3 Short, steep upslope, tree branches force low if right, wide if left
#4 Long, steep upslope, scattered trees throughout, two long slight left-turners
#5 Short, steep uphill, open, a few trees late
#6 Very long, rolling/flattish, multitude of scattered/dense trees, going right a bit more open
#7 Short, downslope, few scattered trees mid/late, straight with slight fade at end to find blind basket
#8 Mid-length, rolling, sparsely scattered trees
#9 Short, downslope, right-turner, ob-road left, basket semi-protected by flowering trees
#10 Short, upslope, moderate window late, left fade to reach basket
#11 Short, downslope, moderate right-turner, creek if too long/faded
#12 Long, downslope then flat, creek crossing with two possible windows
#13 Mid-length, steep uphill, open, a few trees late
#14 Long, cross-slope, scattered trees, choice of right-turning windows, basket well-guarded late
#15 Mid-length, flat, sparsely scattered trees, moderate right-turner
#16 Long, rolling, lots of scattered trees, right-side more open, but adds length
#17 Mid-length, valley, scattered trees, slight right at end
#18 Long, steadily downslope, scattered trees initial 3/4ths
The six (#'s 4,6,12,14,17,18) par=4 are challenging but obtainable. About half the holes should offer possible birdy opportunities - only a few holes will probably score practically only 3's.
This is a very solid course, and will well-complement the other courses being used for the 2019 AM Worlds. Comparatively short to the others, but the relentless variety of elevation changes and out-of-bounds make it stand out.
