Pros:
Radcliff DGC is a very hilly park style 18 hole course. You'll be traversing hills the entire time. There's not a single flat hole on the course.
The baskets are DGA Mach's of some sort. These catch alright. One basket and pin position per hole.
Concrete tee's on each hole. These are amply sized and have good traction to them. No complaints with these. One tee pad per hole.
There's at least a couple trees to contend with on every hole. I don't recall there being any wide open holes. So at least there's always something to force a shot shape. The flow is solid. I'd still recommend having a map available to avoid doing any more walking than necessary, especially with all the hills.
The tee signs are nice. Basic hole map with next tee arrow. There's also the hole #, par, distance and any applicable OB. Doesn't seem like much help but with some of the baskets placed directly behind a tree and not visible from the tee the map was actually very helpful.
Free to play and probably not ever too busy. The course loops back to the parking lot midway through which is much appreciated for a hilly course like this.
Cons:
Very repetitive feeling course. Throw it up a hill, throw it down a hill. Most of the holes just look and feel the same. Not that there's much that can be done about this, but it just starts to blend together.
The course looks like it turns into a waterfall after heavy rains. They recently replanted grass on the holes near the parking lot since it looks like it gets washed away. These two areas were extremely muddy. Thick, thick mud too.
A couple holes throw over the park road which isn't an ideal situation. There's a long walk from 15 to 16 and from 16 to 17. Not really obvious without a little extra walking to find it without a map.
Holes 2 and 3 play pretty close to neighboring yards. Especially hole 2.
Other Thoughts:
This is a decent course, just nothing really memorable about it. It's worth a stop if you happen to be passing through and have an hour or so to kill. If you want a similar type of terrain but more wooded then there's always Muldraugh just up the road.
