-This course has some of the best signage that I have seen. The holes, for the most part, are easy to find and all along the trails there are constant arrows telling you where the next hole is.
-It also contains brand new baskets, each one with another 6 foot flag on top of it to identify the hole from a distance.
-There are a few neat holes that cause you to go back to your bag to change your disc before you throw, but these holes only make up a small minority of the course.

-The design of this course is almost obviously from a ball golfer or someone with very little DG experience. When I first examined the signs, there were "roughs" and "intricately carved fairways" to each the holes, but in reality you were throwing across a wide open field with no distinction in the grass.
-Even with the incredible signage, my brother and I were unable to find holes 13-16. If these holes exist, the signs led us to 17 and we searched for 15 minutes around the area and never found 1 of those 4 holes. According to what I found in an article in the local newspaper, these holes may not be complete yet. If I was around here more I would go argue to the township board to let someone redesign these last 4 holes before they too are ruined.
-Between hole 5 and 6 there is a ten minute walk and hole 18 and 1 end pretty far from each other which is a little frustrating.
-The course never crosses any walking paths, which is understandable because they would like to protect the kids and families that walk through the park, but gets to be very obnoxious. More on this in "other thoughts"
-The tee boxes are a 10 foot egg shaped plot of grass with gravel outlining it. I played this course following a long night and few days of rain and the tee boxes were a mess. With just me and my brother playing and throwing two or three discs on each hole, the front of the tee boxes were torn apart, slick, muddy, and some of them had already begun to erode where the gravel meets the grass.
-Hole Review:
Out of the 18 (14) holes, only 5 were not wide open field shots. Hole 1 is a nice "S" bend through some trees which is a short but challenging hole. Holes 2-5 are all in the open 300-500' holes: nothing special or even worth playing. Hole 6 and 7 are a little entertaining, but then again 8-10 are shot across on open field. 10 ends shooting through a small gap of trees. 11 and 12 are again holes that show some of the potential that this course could have but any shot seems to still end with a basket sitting in the middle of a field. Hole 17 and 18 are fun to play and are heavily LHBH favored.
-The openness of these holes also provides little protection from the elements. I played on a windy day which made putting impossible and some of the open holes at least somewhat challenging because I threw against 25 knot winds, but you could play one hole ten times and it would just save you the walk between tees.

-The amount of paths that are around the park eliminate so many potential holes or improvements. If they were to move tee boxes so you cross a path on a drive, this would not endanger any "civilians" because no disc golfer will throw when a person is 10 feet in front of them. I understand the thoughts from keeping a disc from landing close to a path but there is some misunderstanding in the mindset of a disc golfer to not let a disc cross any paths at any time.
-Walking along the course I saw so much potential and great holes that would be interesting, challenging, and fun for all levels. The course, the way it is now, would be too long for most beginners, and not challenging enough for most players who have played for at least 6 months. The pars for most holes are tweeners. It is easy to par, but it would take a horrible throw to bogey, or a monstrous throw to birdie.
-Overall this course just angered me. With how much money they had, and potential of the land around (it contains a good combination of thick pine trees, marshlands, and LOTS of open space, just lacks in elevation change), the course is a huge disappointment. I feel it will have little draw to bring new players into this course, and unless I lived walking distance from the course, I will rarely go back to it. Next time I go to the course I will take a portable basket and make my own holes. This way I can at least enjoy the game at Overlook. With a little bit of DG community support, I hope that we can breathe some sense into the township board and redesign some of these holes to make this course an enjoyable experience for all skill levels. There are other courses around the Lancaster County area that are worth playing and greatly outshine Overlook.
UPDATE:
I played this course again in the beginning of May, 2011. Most of the open field holes have knee high grass and fairways carved into the,. This is an interesting concept but only more of a nuisance to find your disc but not really a problem to throw out of. If these are played as OB, the course becomes very interesting. The new holes (13-16) are nice holes that make use of a few rows of tall pine trees.

Built on farmland purchased ten years ago to develop into a township mega-park, this course feels like more money was spent on it than any other course I've played (unfortunately the design is, well, uninspired). Brand new baskets and very nice directional and tee signs help the course fit in with the many other activities of the "Overlook Community Campus". A couple holes are interesting, including a 200' carry over a marsh on "links-style" Hole 11 and a tee shot on 12 that takes you through an early tree arch towards a green flanked by two big man-made mounds. Hole 18 has a unique tunnel through evergreen trees with front door/back door options, and Hole 6 is an aesthetically pleasing open shot over a gap in an old farm tree/fence line.

The tees are basically ~8'-diameter circles of grass outlined with by a narrow gravel path. They are an interesting concept and allow a nice run-up, but I'm skeptical about how well they will hold up.

The biggest con is that most holes are simply bland long-ish open holes that feel like they were designed by someone who never threw a golf disc before. Holes 3-5 make possibly the most boring three-hole stretch design-wise in Pennsylvania. You could just put two baskets at opposite ends of a soccer field, throw back and forth a bunch of times, and get the idea for about half of Overlook's holes. Hole 17 has a botched teepad location that prevents it from being a good par 3 hole. Layout issues produce extremely long walks between a couple holes. Hole 2 puts pedestrians in danger on a path along the fairway (which you must backtrack to get to the next tee).

Par is not well-defined for many holes, which play as Par 3.5s except for the cannon-armed. It seems to be designed as a red-level course, but I have a hard time envisioning this course attracting beginner/recreational disc golfers because of all the long open holes with no good ace runs.

I generally look at courses as an optimist, but for all the money ($30,000+, according to 6/29/09 township minutes) and effort the township presumably put into the course it's a shame they couldn't get a more fun/challenging/professional layout that could engage both recreational and advanced players (or at least one of those two groups). Apparently, early course designs for the course done in conjunction with a certified course designer were jettisoned after a change in park management. It's not ideal disc golf terrain, but it still could have suited a pretty unique and fun-to-play Par ~60 course with a unique "links-style" feel close to a large population of prospective disc golfers. Because of design issues, though, the course really feels like a lost opportunity and a setback for disc golf.

All-but-twenty-year-old Buchmiller Park on the other side of Lancaster City still far outshines Overlook Park for while/blue/gold players as a much more interesting course to play with many holes framed beautifully by challenge-inducing trees. Roland Park, too, in Akron also has holes that make you excited to play disc golf. And consider the wonders of youth-pastor-with-low-budget-produced Camp Sankanac DGC in neighboring Chester County. Overlook, on the other hand, would seem to make an outside observer wonder what's so appealing about disc golf. Hopefully, some of the problems I mentioned will be addressed as the course matures and perhaps they can find ways to create a more engaging course.
