Good DISCathcers on every hole, great tee signs on every hole, good concrete tee pads on back 9.
Front nine is pretty easy to see where you are going, its pretty much wide open, in fact, from the parking lot, you can probably see 8 of the 9 baskets. Beginner and family friendly.
Back 9 (actually 8) is more challenging, with large old-growth trees to shape your shots around, but no underbrush to hide discs.

No tee pads on front 9, maybe these are coming since the back 9 are done. Markers are in the ground, but some have long throws and tee pads would be nice.
Back 9 has a couple of baskets only about a foot in front of trees, if you overshoot the basket, you would have to waste a shot to clear the trees.
No benches on the course and there didn't appear to be any restrooms or water.

Since I've used "A Tale of Two Nines" before as a title, I decided to recognize the West side of the course with this one.
The East side (front 9 plus #18) is in a flat, open, little used part of this park. The tennis courts are worn out, the basketball court is worn out (gasp! here in Indiana!), and no playground equipment, so I don't imagine this part of the park gets much activity.
The West side has new playground equipment and swings that probably stay busy. I think they did a good job of avoiding interferences on this part of the course, with these superior holes.
As I mentioned, they have nice, ample concrete tee pads, the holes are more challenging and even a couple of memorable holes. #12 is a downhill, right to left hole that follows the bend of Grassy Creek (the picture doesn't do it justice), a fun hole!
#18 (back on the East side) is an interesting finishing hole. Short at only 196' but it has an island green, with a parking lot and drive on the left and behind, a small creek in front and Grassy Creek along the right. Play it like an island green and its a challenge.
Not every course has to be Championship level, the front 9 is a good warm-up and you can let it fly, the back 9 brings more challenge in your shot shaping.

Still fairly new, Grassy Creek has a front nine in the fairly open section of a multi-use park, and a wooded and more rolling back nine just across the bridge in the southwest section of the park. Excellent signage with hole layout and distances (and bag hooks) adjoin natural tees marked by the ground-level, red, Innova tee markers that allow for easy mowing and maintenance. A practice basket by the parking area, picnic table and port-a-potty, joins the other 18 brand new DisCatcher Pros that are easily spotted most of the way. Hole distances range from 178 to 452 feet (easy to justify them all as par threes for the average player), but there are also white blocks embedded closer to the first nine baskets for kids to throw shots from a lot closer, where there's virtually no chance of losing a disc.

For a little more challenge, the back nine rolls along a slight rise and amongst large, mature park trees beside a pretty creek. Hole 12 is especially scenic, running about 300 feet right to left and downslope toward the creek. There's even a tight double mando on the shortie back there on 15, where control off the tee tends to really shorten your glide, meaning it's not just an ace run. There are opportunities (especially on the wooded back nine) to shape shots in both directions, and to learn how to adjust for the slight elevations back there. You even finish back in the open on the east side of the park with an island green 18th. Not very long, but you've got the creek crossing in front and on the right, and the driveway beyond. A fun shot.

My biggest concern was the number of times I saw a park bench, picnic table, or even a basketball hoop in the line of flight. Probably occurring on half the holes, (or at least it felt like it), you do play over an old baseball field bench on 5, right at the parked cars on 6, along the neighbor's fences on 7, and right at the basketball court on 8. You have to walk across the 13th fairway to get from 10 to 11. The rhbh hyzer line on 16 goes over another parking lot and picnic table, and the hyzer lines on hole 17 for lefties and righties pass over the baskets on 13 and 16, respectively. So there are safety concerns if the park is busy, or if they want to hold a 'full' tournament here.

Although there were some next tee signs, and there's a course map and scorecard available at the hole 1 kiosk, it's a little confusing for first timers to head to the other side of the park for hole 10. Walk across the paved lot, beside the building, and then left, over the bridge, and the 10th tee is just down the slope past the guard rail.

The wooded half definitely has poison ivy on some of the trees and down on the creek banks, and might get a little buggy as well during the wet seasons.

Overall, this is a very nice course, where we were actually saying, if I lived here, I'd play this often!

My buddy was driving, and glanced down at the Nav, then felt terrible about driving over a guy's Ace Race disc on the way out. If he wants, we'll have a half dozen to choose from after the 24th, if he wants a replacement. Message me here. So Sorry!

Reviewer Background as of this writing: age 54 w/ 4 yr experience, rated 900+/-, played 238+ courses in 23 states, 80% w/in 3hr drive of Cincinnati. Thrown with folks rated 600's to 1000's, ages 9 to 85 in events and leagues at all tiers. Seldom drive beyond 300-330, but have a solid up-shot and putting game. I haven't designed any courses, but try to lend a hand (with my severely desk-job limited skill set) when I can.

-Odds are that around this area, the typical disc golfer is not a seasoned veteran due to the limited number of courses so the difficulty of this course is good for beginners to low intermediate.
-Fun use of mando's on #3 and #15.
-#1 is a good warm-up hole.
-#11 and #14 provide good use of trees.
-Good hole signage
-Water is in play, but you won't lose your disc if you throw it in since it is shallow. (big plus for a water course for me as I cant stand losing discs!)

-Most of these holes play very close to each other, so if you see a lot of people playing, you might want to pick a different course in order to not get hit.
-This course is very easy and could have some more difficult pin locations.
-#6 is a hated hole (by me) since you throw at parked cars and over a building so a near perfect drive is necessary to be safe from other people/car damage.
-Lack of concrete tees or even flat tee pad areas causes concern of sprained ankles on a few holes (especially on the back 9)
-youth pads are hard to see
-Needs to have all par 3 scoring for pro style play

This is a good course to get out and throw for low scores for veterans, especially on the front.
-I played especially well the first time I played there (-8 according to course standards) and even eagle'd 14, which i believed to be the 2nd or 3rd hardest hole on the course.
-This course does not have a lot of space, as I played the second and third time I tried to figure out if there were better uses of space for the area they had to work with. I couldn't really find any better places for things in this park so props for that.
-Overall, I rate it a 3 out of 5.

Solid beginner to intermediate level course that spans across both East (holes 1-9 and 18) and West (10-17) Park in New Whiteland. Playable by any age of disc golfer.

Baskets - 18 brand new Discatchers that catch great. Only one pin location per hole. There is also a practice basket near the defunct concession stand.

Signs - 1 sign at each hole that includes a map, distance, par, location of next hole, and sponsor. There is also a course map at the start that lists info about disc golf for newcomers. When needed, there are signs pointing you towards the next tee.

Tees - Tees at this course are natural. Regular tees are marked by two red disc sized markers in the ground that are easy to spot. Tees are level for the most part. 1-9 have dual "junior" tees that are short and a straight shot to the basket. Junior tees are marked by a 1' x 2' white block that is easy to spot. These are listed on the signs for the hole as well as course map. Fiance played from junior tees and absolutely loved it.

Variety - Front 9 is almost completely open minus a few trees, concession building, and some fences and is mostly flat. 4-7 have elevation changes. Holes 10-17 (located in west park) are the signature holes. These holes have multiple trees that create a shaded canopy. 11-16 have significant elevation changes in addition to the shade. 10-12 have a small creek creating more challenge. Even though it was wide it was less than a foot deep. 17 is a tricky downhill shot with a few lines due to the trees. Hole 18 (East park) is a short high risk high reward shot with a creek beside the hole and near the basket. Distances vary from 175ish to 400+ feet.

A few Mandos (3, 8, and 15) create additional challenge.

Benches and trash cans thoughout course. More benches in west park where the shade is.

A playground at each park (East and West).

Course was easy to navigate thanks to the signs and course map. For first timers, could be difficult from hole 3 to 4, 9 to 10, 15 to 16, and 17 to 18. Use maps!

Multiple options outside of course for food and snacks if you go north on highway 31 (gas stations, grocery store, fast food).

Much needed course for the area, especially with a crumbling Freedom Park. Compliments Blue Herron.

Very peaceful park inside of a neighborhood.

Several baskets near road, parking lot, other holes. 2 and 3 are next to parking for basketball area, cars will park around basket. 6 and 8 are within 10 feet of parking area. 9 is 8 feet from a road into park. No issues on back 9.

Several fairways border each other or houses which can cause issues if busy. 7-9 all border each other. 6 and 7 borders several houses with fences (trespassing issues?). 11 and 12 could share a fairway if not careful. 16 and 17 get pretty close as well. This is only an issue if course is busy, otherwise it shouldn't be a problem.

Have to cross hole 13 fairway to get to tee of 11.

Besides safety issues, my next biggest con is poison ivy in West Park. The Mando trees on 15 are covered with poison ivy. Be careful. Bring sanitizer.

I do not mind natural tees if they are marked. Some people will complain about a lack of concrete or gravel tees.

Why are the junior tees only holes 1-9? Holes 10-18 need these too. It would be still be challenging and would elevate the game of a junior player. The markers would not cost too much more to add to every hole.

Could use a few more directional signs from holes 9 to 10 (East Park to West Park) and from 17 to 18 (West Park to East Park).

This was a great course. I will definitely come back if I get the chance. If I came back, it would be because of holes 10-17. The holes in East Park are too open for my liking. If trees were added to East Park, it would change everything.

East = completely open and mostly flat. West = Hilly and wooded aka technical.

Honestly, if given the chance I would rate this a 3.25. It's better than a 3 but not quite a 3.5. The openness and shortness of the holes in East Park would made me lower my vote. When/if the course adds trees to East Park, I will update the review after replaying course. If each hole had concrete tees and a junior set, I would definitely give this a 3.5.

I would recommend this course to any beginner or intermediate player. It's a great course to practice any type of shot. Advanced players will enjoy West Park. It's a short drive from Greenwood, I-65, and even from Franklin.
