Pros:
1) Combination of holes in the woods (3,4,5,17); holes with trees to navigate (1,2,12,15,16,18); and mostly wide open holes (6,7,8,9,10,11,13,14)
2) My favorite holes: #3 is a RHBH hyzer up a fairly steep tunnel of trees; #5 is a short wooded tunnel with a slight incline that really makes me think because the basket is slightly on the right side of the tunnel (requires an ever so slight left to right (RHBH) shot); #17 starts off like #5 but then opens up down hill -- I can count the number of times on my left hand that I've actually nailed that hole. (My right hand has a disc in it.)
3) Concrete tee pads. Chainstar baskets. (I'll still have nicks in my discs from the old baskets that used to be there.)
4) Benches and trash cans throughout the course; it's a clean venue that is used primarily for dog walking and disc golf.
5) Some courses navigate a pile of park amenities and people taking advantage of those amenities; not the case at Tall Grass.
6) Generally, this is a very fun, playable course. I've played here hundreds of times and will probably play a few hundred times more.
7) Friendly disc golf community and club (Flying Lea Disc Golf Club).
8) Oak Island DGC (18 holes) is right up the road. Nice to have 36 quality holes within such a small geographical area.
9) Practice basket between 9 and 10.
Cons:
1) Two or three too many wide open holes (see list of wide open holes in the "pros" section).
2) Needs one two more holes that take advantage of the woods and reward technical ability over power throwing.
3) Parking lot is gravel, with lots of pot holes, but once you're there playing disc golf who cares.
4) No restrooms or water, but there are both at Oak Island DGC.
Other Thoughts:
Tall Grass DGC serves as a very nice contrast to Oak Island DGC (again, right up the road). I've had better success at Oak Island DGC because it doesn't reward power throwers as much as Tall Grass does. That said, if I just want to get out and throw my arm off, I head to Tall Grass. On other days when there is a pile of wind and I don't feel like fighting it, I head to Oak Island. At the moment I feel the Tall Grass DGC rating is a little low because it started off baskets that would destroy your discs. Now that those baskets have been replaced and the course has matured nicely, (being kept up by a few dedicated league members), I'd recommend it to anyone.
