Old Farm Park is a decent sized park tucked into a residential neighborhood in Kentwood (Grand Rapids), MI. There isn't an old farm anywhere in sight, but maybe there was one back in the day.

All 18 holes here have small-ish cement tee pads, a color tee sign showing the flight path and distance, and a yellow band DISCatcher basket. All are showing their age, but still in acceptable condition.

There is good variety here for the size of course. Some holes are tight and wooded while others are totally open. There isn't a ton of elevation change but the small amount present is well used. A couple of the baskets are placed on sculpted mounds, adding a little bit of additional risk/reward.

This course provides good challenge for beginners/amateurs, without too much risk of losing discs. If you play in the summer, the only water holes are #15 and #17 (near a pond). At wetter times of year, small creeks/wet lowland areas are also in play on holes 2-6, 8, and 12-14. The only real concern for a lost disc here is the pond though, and it's not difficult to play it safe on both of those holes.

The biggest issue with this course is safety. Simply put, this course is dangerous. It requires you to have a very watchful eye as well as a willingness to communicate with those on holes around you. The course is very cramped and on almost every hole, a shot that is only mildly errant can find one or more other fairways or tee pads that are close by. For example...the first tee is a wide open throw at a basket just over 200' away. The #2 tee is just under 200' away, tucked to the left of #1 fairway behind a couple trees. A RHBH shot that fades just a little more than you intended can easily find this #2 tee area. Similarly, the #4 tee is slightly behind and to the right of the #1 basket. At less than 250' from the #1 tee, an overthrown drive can easily find this tee as well.

For just one more example, hole #5 is a tight wooded dogleg right. After this hole you walk almost all the way back to the #5 pad, to find the #6 pad. #6 is a tight wooded dogleg left with a basket that is less than 50' behind #5's (so the fairways for #5 and #6 kind of make a square). There is a mando on #6 to force you to avoid interfering with hole #5. Problem is, if you overshoot the mando by 20' you are in #7 fairway. If you overshoot by 40' you are in #8 fairway. On a better course hole #6 would not exist - you would move directly from #5 basket to #7 tee pad. There are several more areas like this where it feels like the designers were just trying to cram holes in to get up to 18.

In addition to the concern with other DG'ers, this is still a multi-use park too. #6 and #7 play close to a pickleball court. Well-travelled walking paths run close to fairways or baskets on about half of the holes. There are a couple of blind throws.

The course is very short. There are six holes under 200', and only three holes are over 300'. The three 300'+ holes are all wide open with no obstacles between the tee and basket.

No kiosk or course map. To be fair, this isn't really needed since everything is so crammed together. But having a map posted is never a bad thing.

Animal droppings, especially near the pond.

I know everyone likes 18 hole courses, but this park might honestly be better as a 9 hole. It has good variety in terrain for being in an urban area, and I can see how some challenging and interesting longer holes could be carved out. For example, combining holes #1 and #2 would result in a 375'ish hole that plays straight up an open fairway at first (current #1), then kinks left and continues down a tightening approach and over the creek to a wooded green (#2).

I have played this course four times now. For the 2nd-4th visits, I tried to come play at times when I thought the course would not be busy (like on a weekday afternoon before 9-5ers get out of work). Unfortunately on each occasion a bunch of other people had the same idea so my experience has been the same: Lots of time waiting on tee pads for other groups to not only clear the current hole but also tee off on the next hole to get out of firing range. Lots of errant discs flying nearby and landing on my hole's fairway (and to be fair, I've thrown some off-target shots too). Lots of time waiting for walkers on the paths.

It's easy to see why this course is popular. It has decent variety and challenge for beginners/amateurs, and is located close to a large population base. If I could have this park to myself for an hour and play the course without safety issues, it's a solid 3.0. But as it stands now I have to knock my rating down a full disc to a 2.0, and it feels like there should really only be 1.0 discs flying at a time on this course.

UPDATE NOVEMBER 2021: Just played the course for the first time in a year. I did not change my rating. As is, this course offers 18 fun short holes but there are lots of safety issues, both with DG'ers on adjacent holes and non-DG activities. I stand by my comments above about how it could be a nice 9-hole course. On this cold November day, no one else was in the park so I was able to 1) enjoy a safe round on the course as intended, then 2) dream up and play a 9-hole safari-style layout! I think that there is a really nice layout, as follows (all walking paths still play as OB):
Hole S1: Play from hole 1's tee to hole 2's basket. A nice starting hole as I guessed it would be above. Right side of the fairway is OB path/across path area for the first 150' or so, A nice drive here will get you to hole 1's basket, and fade off to the left for an easy approach and par. For a chance at birdie, bigger arms would have to throw an understable LHBH or RHFH and get a little lucky on the tight approach. 375'ish, par 3.
Hole S2: Play from hole 3's tee to hole 4's basket. Use the double mando from hole 3, and watch for players on hole S1. When you are only throwing 100', it's pretty easy to make it through that narrow gap 50' off the tee. Not so easy when trying to wind up with a real tee shot, eh? Steady curl to the left the entire distance, with OB path if your RHBH drive doesn't get enough hyzer. 300'ish, par 3.
Hole S3: Play from hole 5's tee to hole 6's basket. This is a lot like current hole 5 except that it is about 50' longer. Or you could try to throw it up the hill past hole 6's tee and follow that fairway around to the left. The middle is thickly wooded so it's kind of a multi-fairway hole here. 250', par 3.
Hole S4: Play from hole 7's tee to hole 9's basket. You'll throw out of a wide tree gap then it's a slight right turn and approach through the open field. An OB path runs across the fairway at the treeline. 350', par 3.
Hole S5: Current hole 10. No obstacles on this one, but it does play up a shallow incline and the basket is raised at the center of a rock formation. 350', par 3.
Hole S6: Current hole 11. Back down the incline. OB path behind the basket. 350', par 3.
Hole S7: The hole that 2 out of 3 DGCR Diamond-level reviewers are calling the signature hole on the course. Play from hole 12's tee to hole 13's basket. Use the mando as signed on hole 12. Hole 12 is my favorite on the current course. The mando tells you to keep left, but there's thick rough and a creek over there and the fairway curls to the right around it. If you get too much curl, there is another OB path. The basket for current hole 12 is only about 240' off the tee, but the fairway for DFrah's hole S7 continues to wind forward between the creek and path, then gives way to a thick grove of tree trunks as you approach the correct basket. 400'. I'm calling this a par 4, because I took a 5 both times I tested it.
Hole S8: Play from hole 15's tee to hole 17's basket. Just when you are trying to catch your breath after hole S7, you walk up to hole S8's tee. This is a true water hole, with a deep pond lurking along the entire left side of the fairway. You tee off from the top of a small hill, and the shortest path from tee to basket crosses the edge of the pond from about 225'-250' off the tee. Can you clear it? 325', par 3.
Hole S9: Current hole 16. An uphill ace run with no obstacles. But hey, who doesn't like to end the round with a birdie or ace? 225', par 3.
Practice basket at current hole 18's basket.
My best score trialing this layout: +3
This 9-hole layout would be much more challenging and interesting for any DG'ers beyond recreational level. More importantly, it would be a much safer course. This layout completely eliminates the largest current safety concerns (throws near a restroom building and pickleball court), and greatly reduces the cramped feel and chance of tee shots hitting other players. There are still walking paths in play but nothing nearly as egregious. If this layout was implemented (along with refreshed infrastructure, etc.) I would give it about a 3.0 rating despite being only 9 holes. If you are amused and play my suggested layout, please DM me and let me know what you thought and how you did.

Decent Discatchers. A couple cool basket placements (holes 10 and 18). Some other decent short, technical holes.

Tees too close to baskets in many spots. Tees without concrete are rutted messes (but concrete coming this Spring).

Good beginner course. A couple of the mandos are silly, trying to make up for poor design. Not sure if they weren't allowed, but I would have used the pond more for a couple holes.

*Great Putting Practice*
Both a pro and con. Most holes are around 200' or less. Great for working accurate mids and placing putters.
*Well Maintained Baskets*
DISCatchers in good shape don't spit TOO many out.
*Good Layout*
Easy to follow course layout (mainly because it's so small) Begins and ends at parking lot.
*Variety*
Decent variety of wooded, open, water holes, L/R and R/L. Some elevation change, but, not much. This slight variety is a life-saver on such a small plot of land.
*Restrooms*
True, concrete restrooms with stalls and sinks. Not to be underappreciated!

*Painfully Short*
Great for putting practice, but, don't expect to drive more than a midrange disc more than twice.
*Graffiti*
Lots of crude graffiti all over signage and benches.
*Crowded*
While they did a great job placing 18 baskets in such a small plot of land (and not having much overlap/risk from other players) it still backs up quickly as you have groups trying to push through a course that totals only around 4000'.
*Community*
I hate to say it, but, the community is rough. Lots of kids who will try to steal discs or hassles you throughout the round to trade something they found for your premium plastic - Lots of groups of 6-10 who rarely let people play through and respond negatively when asked - Little respect.

While they did a good job fitting 18 holes into a small park, it is very, very short. The equipment is well maintained and the dirt pads are decent, but, the people who frequent the park are less than optimal.

My girlfriend loves the short course for practice (playing about 2-3 times a week) but for experienced players it grows boring quick and can be a hassle to grind through.

Lots of fun for competitive putter-only rounds.

*I like some of the longer holes. The elevated basket surrounded by boulders on number 10 is especially creative. The 15th along the pond is really well done as well.

*Ugly and vulgar graffiti on the tee markers. It makes it look like most of the people who use this course are 13 years old.
*Most of the holes on the front nine are too short.
*Most of the holes that go through the woods lack any legitimate line. It's more luck than skill.
*Many of the longer holes simply go back and forth across a relatively flat open field.
*Dirt tee areas are muddy and potentially dangerous due to roots.

I have played this course many times, because my mother in law's back yard touches the park. This is the only reason I would have played more than once. This is one of my least favorite courses in the area.

As of March, 2013, the tee sign for number 18 is missing.

-starts and begins at the parking lot
-good short and mid practice
-good signage

-dirt tees are really uneven and full of roots
-middle of course very unimaginative
-other golfers and park goers tend to get in the way of the tightly placed holes

This was a short course without a lot of distance or variety. The middle of the course seemed like they just ran out of ideas (3 or 4 holes are just back and forth in a wide-open obstacle-free grassy area). The other golfers and park goers tend to get in the way of the tightly placed holes. It could have just been the day I was there but it doesn't seem like there's much respect for disc golf etiquette. My biggest problem with it would be the tee pads. They're dirt which isn't normally a big deal to me but these were so uneven and often had tree roots that became quite the tripping hazards. I wouldn't go too far out of your way to play this course but if it's close by it could be a good course to work on your mid and short range games.

-Beginner friendly, with generous amateur tees.
-Adequate signage, obvious flow, and a fair balance between short wooded holes and somewhat longer drives across a grassy field.
-Good use of the little elevation available, including a basket raised a few feet by rocks.
-A pond and small creek come into play on a couple of holes, but only the most errant throw risks being lost.
-Mandatories add to the difficulty in several spots, although one sign was missing (thanks to Terry C for guiding!)

-Well-worn dirt/natural tee pads are fairly treacherous. Beware roots, they'll push you down and steal your lunch money if given half the chance.
-Located in busy multi-use park. Some trash and graphitti.
-Due to the close proximity of each hole to it's neighboring holes, the chance to be hit by a disc is very real. Exercise caution when busy.

-Pitch and putt except for a handful of moderate length holes.
-A fun little course for casual play or if you're in the immediate area.

Nice baskets. At first when we drove up we thought the course was going to be pretty nice. If you are looking for a mid range or putting course it would make an awesome course. This would make an perfect beginners course.

Very short holes. Being a women and just starting not long ago these baskets are still not very challenging for me. I didn't feel challenged at all. I was able to drive it to the basket no problem and even overdrive it on some. Seriously I dont know why they have ladies tee pads at this course. Plus the baskets are right on top of one another so you have discs flying at your head the whole time. Could use some concrete tee pads.

If you are just starting this would make a great course to start at. It was a very busy course with people on top of you and discs flying at you the whole time. Other than that if you need to work on your short game this is a great course if its not busy.

City keeps it up nice, nice baskets, good scenery, nice tee signs (need distances marked though)

Terrible design, many of the holes you end up crossing other fairways and you are always waiting for someone to throw from your fairway to a different hole. Tee pads are located right next to baskets so you always have to watch for discs flying at you. Very busy, with a mix of serious players and not so serious players so the rounds are very slow. You could play this whole course with a putter and a mid-range...very short. Its like they tried to put 5 lbs of cow patty in a 2 lb. bag.

There was nothing about this course that would bring me back to play it again.

-
Fun and quick. Technical with a good mixture of tight wooded holes and open fairways. Good variety with water and slight hills. Signs are sufficient and the holes are close together so it is hard to get lost.
Good baskets.
Nice scenic park, good landscaping on some of the holes, nice bridges.
Water hazards.

-
-Lot's of people.
-Busy park with people walking through fairways, playing basketball and lot's of golfers.
Dangerous set up of course.
-I was constantly looking behind me at the group coming up.
-Fairways are to close for my comfort on some holes with minimal protection and head on collisions possible.
Natural tee pads make spring and rainy days less enjoyable due to mud and slips.
Mando signs gives a big advantage for righties.
(sorry not a fan of mando's!)
Course favors righties.

-
Probably would not play course again. I imagine it is better in the summer when the ground is harder and your not worried about falling.
Try to shoot basket 18 from on top of the cement building for the longest drive of the course! (the kids will cheer you on!)
