Pros:
Tons of parking near the practice basket and the first tee. The practice basket has a nice sized area on a slope to practice coming from above and below the basket.
The course sign has all the information you need. Take a picture of it if you need help with navigation... but you shouldn't need help with that since each tee has an 8 foot high pvc pole with yellow on top, and the basket locks point roughly to the next tee. The only tough spots are 3 to 4 and 12 to 13.
The tee signs are very nice. They have been updated since the 2014 pictures and have more accurate distances. The tees themselves are fine size-wise, but I'm sure some people with big x-steps might need more room. Yellow Chainstars are easy to see and still in good shape.
So much variety through the round, tight woods on 1, 2, 4-8, and 14; tough two-shot holes on 3, 10, 11, 15, and 18; looming dropoffs on 8, 15, and 16, and 13 combining all of those to be be best hole on the course.
Several unique holes: 1 has a left-right chicane in the fairway about 250ft off the tee, then the pin out the gap and around to the right; 7 is uphill 275 to the mouth of the hallway, a 90-degree dogleg right, then another 250 downhill to the pin; 13 is my personal favorite: par 4, off the tee you want to get far enough right to have a chance at getting around the trees on your next shot, but you'll have to watch out for the water long on your second shot, then the green is tucked into the trees about 100 feet past the corner of the tree wall; and 15 is a tweener par 5, If you get the drive right you have an easy chance at birdie, and pros could definitely come away with an eagle, but if you get on the hill to the left or caught in Woodhenge it's a tough 5.
A few great gaps, 3 takes away big hyzer lines off the tee, 12 has a late gap right near the pin, and 18's is halfway down, and just thin enough to make you think twice before bombing your drive.
Cons:
The fairway of 5 is almost unfairly thin, hole 9 is a bland 300ft drive, hole 6 is a little too easy so long as you hit the initial gap, and overall the pin positioning is very vanilla, 13, 15, and 18 are the only decently interesting ones.
The end of the course is a long way from where you likely parked (by the practice basket)
Some of the trees need their low-hanging branches thinned out, on holes 3 and 10 especially.
Flooding can become an issue during rainy season. Hole 13's pin is the low point on the course, and the path from 3 to 4 can disappear underwater quickly too. The baskets of 3, 15, and 16 are the other testy spots, but they are a little higher up.
Other Thoughts:
This is one of the most varied courses in the midwest. Holes 7, 13, and 15 are the highlights but they're backed up by a solid set of 15 other holes. There's plenty of distances, shot shapes, and trouble to make this an absolutely fantastic and challenging course.
Woodhenge is completely worth the stop and 6 bucks on it's own, but you get two more courses for that price, too! I recommend playing this course first out of the three since it is the toughest.
