Pros:
Minimal underbrush. The tees are now marked with blue ground markers and there is signage available for the two walks where the next tee is not obvious. There are plenty of opportunities for ace runs. Hole 18 throws off a rise, over a swampy valley to the other side for the most interesting of the shots. (Hole 9 starts from closer and lower to the valley and pin). The course and fairways are well worn in from decent use, presumably from the nearby college. It is laid out in a circular design, giving an easy choice of hitting the "back 9" or simply heading home without a long walk back.
Cons:
The holes feel repetitive except 9/18. The course plays around some mixed use areas but does not directly impact them; however, it plays directly over and across itself. Most tees are from the previous holes' green. If the course is crowded, there would be a fair amount of waiting and it could only accompany 5 groups without feeling very cramped.
Other Thoughts:
Update: The original signage is gone, and the review from 2016 is incorrect on the hole numbers. Holes 1-4 play tight woods shots. Hole 5 is across a field with a few guardian trees. Holes 6-8 play around a softball field. Trees line the left side of hole 7 and hole 8's pin is on the side of a left-downward sloping hill. Hole 9 plays across a valley back towards hole 5's fairway. Holes 10-18 are mild variations on 1-9.
Adding a second set of tees helps open the course up to more use, but most of the second tees are almost the same exact shot, just 10-30 feet back or a hair to the right or left. The only 'different' tee would be for 9/18, where 18 is elevated and further from the pin and 9 is 40 feet closer and starts from below pin height. The lack of thick underbrush is a stark contrast to the other 9 hole tunnel shot course in the area. Miss a shot here and your disc is found in seconds. I'd play it again because it's local and I'm not punished with 15 minutes of searching for an errant shot. It's a great place for new folks who can score par with a beginner's arm. It's better than it used to be with the extra tees, but I wouldn't drive more than 20 minutes to hit it unless I was bagging courses, since it plays in 30 minutes and circles back to the parking lot.
