Pros:
Jericho is an above average course set in a nice wooded park next to a large lake. Many holes play close to a creek that creates a water hazard and adds some risk to shots that are for the most part fairly easy.
The strength of the course is the land it plays through. The front nine begins with a series of short, mostly straight wooded shots, with a wide stream running behind, then along the fairway, of several holes. You'll have a chance to break out your driver on the last few holes of the front nine, before crossing the stream on the back nine.
Most of the back nine is similar in distance to the front, with one or two requiring a driver from the longs, but for the most part, these are shorter shots, with a few tee shots requiring an anny or small hyzer line. Some patches of brush, and a good amount of trees provide obstacles in this section, but I'd still classify this area as pretty open.
I really like the shots that play along the lake, and the creek is a nice touch of scenery as well. There is a lot of seclusion at Jericho, so if you like a course with a good nature vibe, you'll have fun here.
Each hole has two sets of concrete tees, and most intermediate level players and up, will want to pay the longs. The shorts are ideal for beginners. The signs are wooden posts located at the short tees with the distances for both the long and shorts. The long tees are unmarked, but usually easy enough to find. The long on #10 is on the front-9 side of the creek, and throws over the creek; a pretty cool shot, just know where the tee is before you go, or you won't find it.
Cons:
I want to like this course more, but it's just too easy. Even from the longs, a good tee shot should put you well within deuce range, and most above average players should come close to shooting under pro par.
This would be one of, if not the most, beginner friendly 18-holer in the area because of the lack of distance and easy angles, but the water hazards on the front 9, and on #12 pose serious disc losing potential.
The creek here can also flood during high periods of rain, and from what I was told by some guys who play here regularly, this course was pretty much unplayable due to flooding earlier in the summer. This also makes it a haven for mosquitoes, so bring your spray.
The dual tees are very nice, but only the shorts are marked, so if you play from the longs and want to know the exact distance, you have to walk up the post on the short tee.
Other Thoughts:
If you live in the Chicago area, this course is worth a stop. The seclusion and scenery are way above average for the area, and there is enough here for advanced and new players to have an enjoyable round. There is also an Ace Race hosted here during the fall that is worth checking out.
