Pros:
The Kensington Black Locust - Green course is one of three at Kensington Metropark northwest of Detroit. It shares a parking lot with the Black Locust - Blue course, and the Kensington Toboggan course used for DGLO each year is about a 10 minute drive away in the opposite corner of the park. Unlike Toboggan, both Black Locust courses are open year round. The courses are very similar, so a lot of this review will be copy/pasted to/from the Blue course.
This course is well designed and requires a wide range of throws to score well. Fairways range from relatively wide with thick rough on each side, to tightly wooded. #5 may be the tightest here, and requires hitting one of a couple of tight lines off the tee. #17 has one of the wider fairways, playing along a big sweeping 90 degree right turn. The elevation changes on this side of the park are nothing extreme like Toboggan, but plenty to keep things interesting. My favorite hole was #11, which has an S-shaped fairway that plays down and up two different wooded valleys. Unlike the Blue course, there aren't any water hazards on this Green course.
The baskets are what I think is lime green painted Chainstar Pros. I know that they are great. One per hole.
The tee pads are concrete and SO LONG. Some holes have two tees (long + short), and the rest just a single tee. In contrast with the Blue course, it looked like some of the long tees here also offered a different look at the basket than the short tees (versus just stretching out the distance a bit). Regardless of chosen tee, the distances here are nowhere near the grueling marathon of Toboggan but will be plenty to challenge most players. They seemed to be generally slightly longer than those on the Blue course. After a long day playing Toboggan and the Blue course, I was happy to throw from the short tees here and found them to be plenty challenging for my noodle arm.
The tee signs appear at each tee and are green colored as well. They are adequate - with a simple hole number/distance, indication of both tee locations when present, and a rough hole layout. I'd like to see the pars listed on these, and found myself missing them a bit more than on the Blue course due to the longer holes. Periodic trash cans and benches complete the tee areas.
There are two separate practice basket areas near the parking lot, as well as a porta potty. A kiosk including a large map of both the Blue and Green course is posted near the first tee.
Cons:
There isn't any navigational signage. The correct paths between holes are well established, but these could be harder to distinguish at certain times of year (e.g. after leaves are down, or in the winter). Also, while there are easy ways to play fewer than 18 holes here none of them are pointed out so you'd have to use the map on the kiosk (or UDisc) to figure that out.
This course has a lot of fun holes, but most of them didn't really stand out to me. If it weren't for my written notes, even the ones briefly mentioned above might have already faded from my memory as I write this only 11 days later. Perhaps this is partially just because the holes here were inevitably crowded out of my mind by the epic scale of the ones on Toboggan.
Road noise from I-96 just outside the park detracts from the experience. This course is closer to I-96 than the blue course, so the road noise is more noticeable.
Other Thoughts:
The total cost to play this course is $13. There is a charge of $10 for a park day pass (payable at the park entrance), plus a separate $3/day disc golf fee (payable at a trailer near the first tee). Credit cards are accepted in both places. The $3 gets you a wristband that allows you to play both Black Locust courses. However, if visiting when Toboggan is open you can get a $5 wristband at that course's parking lot that will also cover you at Black Locust - so if you have the time and energy to tackle all three courses in one day as I did, I would strongly recommend starting with Toboggan (both to save money, and to hit the hardest and best course first).
This Green course and the Blue one are very similar overall. The main difference with this Green course is that the fairways are a bit longer - and maybe also very slightly wider - on average. The small differences are not enough for me to rate the courses differently. They are both solid 3.5's in my book.
This course is not only a great complement to Toboggan, but a solid play on its own. Even if Toboggan is closed or not your speed, visiting Kensington Metropark and playing the two Black Locust courses makes for a fun afternoon of disc golfing and is well worth the $13!
