1) Hole diversity:
--Holes with a relatively narrow tunnel of trees: (1,2,4,5,16)
--Holes with some part narrowed by a tunnel of trees: (3,6,7,9,10,11,14,15,18)
--Holes that cross water: (12,15,17)
--Holes that no one can ace: (6,15)
--Holes where wind, depending on direction, is somewhat of a factor: (6,12,13,15,17)
--Holes right to left (hyzer for RHBH): (5,6,8,10,12,14,15,17,18)
--Holes left to right (turnover for RHBH): (2,3,4,7)
--Holes with very sharp left to right; not quite possible to do turnover: (9)
--Holes that are relatively straight: (1,11,13,16)
--Holes going mostly downhill: (3,6,9,14,16)
--Holes going mostly uphill: (2,5,7,10,~13,18)
2) Cement tee pads that grab your feet so you don't slide around...even on wet days.
3) Sweet baskets. Yellow band at the top helps visibility.
4) Well marked course; nice signs with hole navigation.
5) Benches and trash cans; tons less litter since disc golfers adopted the area and upgraded course was installed.
6) Restrooms, water and picnic tables on the course.
7) Right up the hill from Tall Grass DGC, which is a very different type of course...not as good as Oak Island, but an awesome complementary course.
8) Friendly, committed and well-organized local league: Flying Lea Disc Golf Club; a big reason Oak Island and Tall grass are well-maintained.
