Pros:
Salk Park is Rolling Meadows main park. The South side of the park is well developed and holds ball fields, a soccer field, an ice area, a community center and an aquatic center. About all you see of that development from the disc golf course is the ice arena parking lot and the preschool playground you throw toward on #3. The North side of the park is a flat, narrow strip of land running on either side of a creek. It has a sled hill, a playground, a walking path and a lot of open space. Houses line the park boundary on both sides. The course has new Innova DisCatcher, nice tees and functional tee signs. There are two very good pedestrian bridges and good signage when you cross the creek. Some of the holes have some distance, so it's a good place to air out drives. Hole #4 has an alternate tee on top of the sled hill, which is cool.
Cons:
Other than the throw off the sled hill, this is a painfully boring, repetitive course. The site is lightly wooded and several of the holes are wide open. Holes #2, #5 & #7 are basically the same shot. Holes #8 and #10 are the same shot, just with the creek on the other side. Hole #11 is the same shot as #8 and #10, only with no creek. A lot of this course makes you think "didn't we already play this hole?" Unfortunately, none of those shots are good enough to make you want to play them again.
The walking path winds through the course, and on holes like #2 and #5 it conflicts with the entire hole. I noticed four times that people walking on the path kept looking back at me, like they expected me to throw on them. I got the impression that this multi-use wasn't working out very well.
The golf is meh. The lack of obstacles and elevation means you basically throw the same shot over an over. The only scoring separation you get is from the difference in distances people are throwing.
The course is 12 holes, but the holes conflict with each other. The area where #6-#7-#8 are is a head-scratcher. There is a long walk from #5's basket to the #6 tee for no reason; the #6 tee could be up closer to the walking path and farther back. With hole #6's basket back where it is, hole #7 shoots up past the #6 basket into an area between #6's basket and #8's tee. All of the holes conflict with each other. #8 is a long for long's sake shot next to the creek that could be shortened to get the tee out of the way. #7 could be pulled altogether or #7's tee could be used for #8 if you were not trying to cram 12 holes into a small space. The course would be better with more variety if it was only 9 or 10 holes.
Other Thoughts:
Given that North Salk Park is flat and lightly wooded, it wasn't going to be a great course. It has the potential to be better than it is, though. I think most people find that the fact that it is 12 holes is a pro, but for me I found myself thinking "is it over yet?" by hole #8. A redesign down to 9 holes would greatly improve this course in my opinion. As it is, the course is boring and repetitive. It's an open spot to air out drives, otherwise it is a waste of time.
