Pros:
Nice Innova baskets with yellow ring and red flag on top - easy to spot.
Park/restrooms open 5 am to 10 pm.
Had the whole park to myself on the day I played.
Little chance to lose a disc except hole 3.
Surprising for a little farm town in Amish country.
Cons:
Tees were hard to find - five easily, two with a little bit of searching. Never did find #7 and #9.
Two horse picket lines must be thrown over or around on hole #2.
#3 hole is next to impossible.
#9 hole has a row of large trees in line with the tee and basket.
Low branches on many holes.
Other Thoughts:
A lot of Amish buggies and Amish bicycles on the roads in this area. Please drive carefully.
September 2024 update: Well, I was wrong. The "new baskets/new course" turned out to be old baskets/old course, new tees. The baskets seem to be unaltered. Eventually, they will have 18 tees: two per basket. They are slotted poly/plastic that I have seen at other courses. Currently, 15 or so are installed. Tee two is still the long throw over the horse picket lines, so good luck on that one. I've increased my rating from 2 to 2.5. Also, if you have kids, the large wooden playground set is soon to be demolished and replaced by a larger plastic play area. It may be roped off for a while.
October 2023 review: Played on a Sunday morning after three days of showers. Was surprised that there was no standing water. All the Amish were still at their meetings. I've been to Delt Church Park when there was 100+ buggies. I would expect the same here on a sunny weekend. Park in front of the pavilion. Restrooms were open on 10/22/2023. I remember in my hometown everything was locked up the day after Labor Day. Grass was shorter near the pavilion, cut longer (4") further away. Bright color discs a must.
I was surprised at the facility. Millersburg is a tiny town. The "downtown" shopping district consists of a single store - Dollar General. The park has two volleyball courts (one net up), a huge playground, a gravel jogging loop with exercise stations, two basketball courts, four baseball diamonds and a half dozen sets of all-weather cornhole games (bring your own bags).
There is a row of pine trees on the far side of the volleyball courts and another one on the right side when standing at the pavilion. Tee one is under the row of trees to the right.
Tee two is between the road and hole one. This one will be difficult, throwing over/around the horses and buggies during an Amish gathering.
Hole three is near impossible. Low (7-8 foot) branches and a 15-foot wide "runway for 200 feet then a left turn along another runway with low branches for 200 feet, then the target is in a gap in a row of trees to the right. There is some rough, two-foot-tall grass that you could throw over to "cut the corner". It was laying down on my visit in the fall. I can imagine it swallowing a disc in the summer.
Tee six is right next to the access road. Your run-up will be on the road. Hole six is on top of a man-made hill.
Never did find tee seven. Pacing back from the target 289 feet, it should be right at the base of the hill, near the steps. More fun to throw from the top of the hill. Careful on those steps - an accident waiting to happen.
Did not find tee nine either. Pacing back from the target 281 feet puts you between the road and the closest corner of the first basketball court. From there a row of trees, again with low branches line up with the target. That puts you back to the parking area.
I will probably play this course again as there isn't much else in this neck of the woods and it is a nice bike ride on the rural roads.
