Pros:
This course is decent because overall it is pretty sound. What brings the rating down is mainly based on the experience as a whole, what could have been with the surrounding land, and other intangibles. The uphill and downhill runs are not long bombers but pretty strategically placed so that you need some control over distance. The course makes good use of trees in the area, but could be much better by simply diving 200' or so into the immediate woods. The balance (left, right, straight) is great. Uphill, downhill, acrosshill is a good balance.
Cons:
The park itself is run down and full of slobs and worthless useless idiots who vandalize and generally do nothing useful for the course or society. The tee areas SUCK. They are huge eroded dirt areas with no clear edge or sides. They are also rutted and muddy after any kind of rain. There are also quite a few soft wet low spots you almost have to walk through to get from hole to hole. The tee signs are in poor shape. There is garbage and broken glass everywhere. Baskets are generally poor and bent up due again to those idiots I mentioned.
Course design is adequate at best though, mainly based on the features. Yes, triangle is more fun to play than the other courses in my opinion, but without tight holes and obstacles, it is a deuce or die course. What I mean is that if you are off on your drive, your recovery/layup will be easy as cake because there are almost no obstacles mid fairway or off the fairway - just wide open hills. I dislike any course that plays this way.
The number of non-players, punks, garbage, vandalism, etc just completely takes away any chance at an enjoyable round here.
The Baird Creek parkway is a ginormous park system with some unbelievable monster terrain and features! This course could have tapped into a bit of that if the planning parks people had the nerve way back when. Not a con to the course, but Traingle could remain the beginner/idiot friendly course, and if the city of GB built an entire new 18 hole course elsewhere in the park people would be RAVING!
Other Thoughts:
The overall experience is definitely lacking and generall sucks due to the human factors. The course itself is sound, but not challenging in the least. The park system could yield a MONSTER course in anyone's book.
Go to Kewaunee and play Winter Park if you're travelling to the area!
I play Baird more than any other GB course because I think they all suck, but at least you get a workout at Baird, may as well have some benefit to the round. If you run the hills while speed golfing, you can get in a round in just over 30 minutes and have one heck of a workout.
The mountain bike trails in the parkway are pretty extensive and fairly challenging, but highly eroded and rooted.
