>> Cement tee pads were installed!
>> A very quick course to play if you're short on time but want to play a round. I played the course twice in approx 45 min
>> A good layout considering the amount (or lack thereof) of open space the park has available.
>> Several holes through trees with a low ceiling give you a chance to work on your accuracy

>> Many of the holes put you in danger of being hit by an errant throw (I disc rolled right in front of me as I left the Tee pad)
>> Short Tee pads
>> Rusty chains on several of the baskets

I thought it was a good course for practicing different throws and trying out new discs. Or maybe even an ace race course. I nearly aced a couple and I'm not a pro by any standard.

A nice community park course for casual to rec players to get their egos inflated, O'Brien DGC has nine relatively easy holes with predominantly open lines to each basket. There is almost no chance of losing a disc here, as the lawns are well-maintained, and the park is very clean. The only place that poses a challenge on that front is going long to the pond on #3. There are three holes over 300' (#1 can be considered so because it plays over 10' uphill - effectively a 30' length 'increase' - on a basket 280' from the tee): #'s 1, 2, & 9.
The first 'tee' is just past the playground and runs across the park to the right side of the hill. Shooting to the second hole from the top of the hill towards the rear of the park was a pleasure for this moderate to weak arm. Then the real ace runs began, with #'s 3 through 8 running back and forth across the gentle drainage ravine, before finishing back towards the playground with a longer, open field #9 basket.
Intermediate (and above) players may look at O'Brien as an opportunity to practice approaches and putts, or just an opportunity to rack up aces on their resumes.
Each hole had a decent tee sign.
The park has play areas, a soccer field, a pond, and a walking path, adequate parking, water, a port-o-let, and other amenities for a family picnic outing.

The tee areas are not well defined, as they are still simply swaths of gravel beside the tee signs, and though they are fairly level, they tend to spread forward and back for about 30'. Based on the pictures and initial course information, it doesn't look like there are intentions to upgrade (though the course seems decently maintained).
Though the flow is usually pretty clear, I always prefer having at least an overview map near the first tee.
Personally, I'm not a huge fan of the Innova baskets with the 'chastity belt' metal rims at the top, but even more so because that's what I hit to miss an ace on #6.
The course is probably too short, easy, and monotonous for a serious player to expect any kind of challenge, unless they need an ego boost like I did (see below).

After the frustration of not being able to complete a tournament in near 100 degree heat on a Saturday (borderline heat stroke), I truly enjoyed playing a couple of rounds at O'Brien the next morning, in part because the weather broke, and a sunny, lightly breezy morning in the high 70's felt SO good. But the other part was that this short, easy course was such a confidence booster for a Rec level player to run 7 straight birdies, I had to grin!

Much improved!!
-Good beginner course
-Nice Discatcher Pro baskets
-One uphill (1) and one downhill (2) hole
(these two holes use a sled hill, 1's basket is on the side of the hill and 2's tee is at the top)
-Water can come into play on 3 (basket is on a rise with a pond ~30' behind)
-A few of the holes require you to throw different lines
-Got my first ace here

-Mostly wide open
-Overall very short (only 2 holes over 300)
-Gravel tees are quite rutted
-This course can be frustrating because you feel you should 2 every hole
-Can be crowded
-The small tree in the center on 5 is gone, totally changing the hole (way easier than it used to be).

If you played this course a few years ago one round was enough. The holes were silly short, the baskets were bent, there was no reason to go back. The redesign has really improved things. Don't go out of your way to play it, but it is no longer a waste of space. Castaldo Park just west of O'brien in Woodridge is much better.

It was fun to bring the family out for a half a round. Super easy, great intro or lesson course. Not too crowded. Some slight elevation changes but it is Illinois so not really hilly.

Not a disc golf only park although there is very little reason to be on disc golf part, because there is enough non disc golf areas.

The play ground is not too close to the course! so you don't need to fret over driving near kids. This is a design that should be used in other multi use park courses.

Short course, not too crowded and good for beginners who are working form but don't have the distance on their drive yet. Some elevation on holes 1 and 2, some locals play hole 10 (from the top of the large hill to the 9th basket) which adds another elevated hole.

If you are a pro or can drive more than 300 ft on average you probably won't need to bring a driver at all.

This course is walking distance from my house so I have played it a lot. Be respectful to the houses lining the course and try not yell too much profanity, there are kids that come and play at the playground!

- New Discatcher Pro baskets
- Maintained gravel tee pads
- All signs fully intact/not damaged and were fairly nice.
- Porta-Potty by the parking lot
- Easy to follow for first time
- Hole #1 and #2 have decent elevation to them
- Not too crowded
- Park was very clean and nicely maintained

- Holes #5-#8 are bland and very alike like the other reviewer said
- Some people flying kites on Hole #1 and Hole #2
- The main con is the design it's just not that engaging
- I felt restricted throwing and couldn't just let a nice drive go
- Most holes are only 100 to 200 something feet long, lacks any holes where you can actually throw a nice drive

This is a well maintained Disc Golf Course but the design really sets it back, however I would play it again for sure, and it's a great course to introduce people into the sport.

Nice baskets and signs.

Great use of the sled hill and elevation for holes 1, 2, and (10)

Better use of park space, though course is packed into a tight area.

Tee pads are dirt and rutted. Have to watch your footing on tee offs.

Can have groups of friends chucking at times which makes waiting to play a short course less fun.

Not big enough to have a legitimate 9 hole course. The only holes worth playing are 1, 2, 9, and making up 10 from the top of the hill to basket 9.

Very short holes 3-8 play across a small ditch with very easy holes and lines to hit for deuces.

It is a good course for the elevation holes, but after a round or two it will get way too easy. I come here every so often to play as I am less than 5 miles away from it. It is good practice but nothing worth driving far for.
