Pros:
The location is a great exposure point for disc golf. Randall Oaks is a very well-known and busy park, and the basket for # 6 is in plain view of traffic on Randall Road. The course does have more elevation changes than your typical Chicagoland course and features a couple of elevated tees and uphill shots. The tees are made from paver bricks and there are good tee signs and markings to help you get around the course. All in all, it's a pretty good course.
Cons:
There is only one 400+ ft shot despite having the space for a least a couple of more long shots that would separate it from you typical Chicago 9-hole pitch & putt. The one 400+ ft shot is flat and wide open, something that is becoming all too familiar to me. Just because a hole is long, that does not mean you can't have any trees or elevation in play.
Despite having a great big hill to work with, only four out of the 10 holes use the elevation to any significant extent. Neither of the elevated tee shots are long enough to throw a driver on. Again, they missed an opportunity to create a course that would be unique from most Chicagoland courses.
The basket for # 4, the tee for # 8 and the basket for # 9 are all right next to each other. If you hyzer your drive on # 8 it will fall out onto # 9's fairway as the fairways are right next to each other, separated more by elevation than anything. It seemed like the entire hole # 8 could have been moved south to avoid these conflicts.
To get from # 4's basket to # 5's tee, you have to walk right past # 7's basket. # 5 shoots over a park service road, and the obstacles are mostly the stop sign and speed limit sign you have to throw over. Really if the course is busy, there is going to be a logjam of people around 4, 5, 7, 8 and 9 because they all come together in the same spot.
There are 10 holes, but hole # 10 adds nothing to the course. Its an 200 ft elevated tee putter drive that is there mostly to get you to walk around to the other side of the parking lot so everyone will exit and enter the parking lot in the same place.
Other Thoughts:
The baskets were set into these big concrete stands that were about a foot and a half in diameter, so there was a big ring of concrete around each basket. I found that a little odd. They were flush with the ground, so it really did not effect play one way or the other.
I was excited when I heard about this course, as I had been to the park many times and had often looked at the hill and thought "I'd love to launch a drive off there." Well, the course is there and is on that hill...but sadly you never get to launch a drive off the hill. The terrain is there to have an outstanding 9-hole course, but instead the course design seems to draw from all the other ho-hum courses in the area and does not stand out significantly from them. It's not a bad course by any stretch of the imagination, but when you look around you can see the potential for so much more.
