The stakes are in the ground.
It's a wide open course, but it also has some new shots. You'll be putting up at some baskets.

I don't know what you call it, but there is like a land depression where it's sunken in for half of the course. There don't seem to be any stakes on the lower land. And I don't know the layout. But it looks like you might be shooting over that sunken land, trying to reach the basket on the top of the "hill." And the "top of the hill"/"surface level land" isn't that wide.
To get to the park, take Rt 34 to Sycamore Rd. Make a left. Drive up a block to John Street. Make a right. The park is just around the bend on John Street. You'll see a baseball field there. Park along the street. (You can also drive up to Diehl Farm Rd from Rt 34, where the Fox Hill sign is. But Sycamore has a traffic light, and is more obvious. Both will get you to John Street).
The course runs the entire length of the park. The stakes are painted blue. They are hard to find. A couple were almost flush to the ground.

To the south, there is a horse farm/training camp (Autumn Acres Equestrian). The horses look cool, but there is an electric fence that separates them from the course.
The last blue stake is far enough from the fence if you are a reasonable distance from the basket. But if the wind catches your disc, or you get a hold of an awesome drive that goes deep...I don't know. I'd have to go back and try to find the teebox stake, to see that shot again. Nothing major, though. It looked safe from the basket location.
