Pros:
18 rubber tees and DisCatcher baskets. Decent navigation with next tee arrows on baskets. Nice variety of elevation changes and mixing up the open and wooded holes and fast greens.
Cons:
Short and skinny rubber tees for the time being (I've been told the long tees will eventually be concrete). No tee signage at the moment although I'd expect that to change soon. The only poison ivy I noticed was by the basket on 11 and along the edges of wood line of the upper holes. There's a bit of underbrush that needs to be cleared and I'd expect this will improve soon as well since the course is brand spanking new, but it's definably playable and not bad at all.
Holes 1, 2, 3 are basically the same open shot with tall rough to the left and the ball fields to the right up the slope. There's potential for errant discs and/or errant balls from the fields to interfere with each other on a number of the open holes, as well as park walkers especially on holes 8, 9, 10, and 18. As previously mentioned on hole 4, the rams to the left could be hazardous for humans and/or the rams.
Other Thoughts:
Overall Codorus Township Park is a good par 3 course(plus a 4) and is an enjoyable play. I was the only disc golfer in the park on Memorial Day and half way through there was a walker in the park that I had to wait on hole 9 to pass. When I was finishing up 17 and 18 there were two more walkers in the park, but still no other vehicles. The course features a lot of elevation and fun factor after the first couple holes and ends with a nice downhill ace run on 18 that I unloaded my entire bag on.
The designers did a good job to mix up the open and wooded holes as best they could and worked with the available land. The wooded holes are mostly short and straight with a very subtle turn, there's no doglegs or continuous line shaping required to play here. That combined with the other half of the course being open makes it feel a little repetitive as throwing/landing straight is the main objective here, but it's still fun. At any rate I'd recommend playing this course if you are in the area. There are over a 100 holes of fun disc golf within 20 minutes of each other between Codorus State Park(54) and Codorus Township Park(18), and Creeping Creek/Brewery (19 or 20) and the new Leister Park in Hampstead opening this summer (9).
