Pros:
Bennett is a small park 9 with a lot of personality. Nine concrete tees and nine blue DisCatchers in place. The course sign by the parking lot shows distances for every hole, might be worth a quick photo since there are no other signs on the course.
Elevation is the big feature here, 2 is way uphill through some tight woods, 3 has some brush right in front of the pin after going uphill all the way there, 6 goes down and back up, 8 is a par 4 that goes downhill to the right, then back uphill and to the left, then 9 is through gaps of trees with the basket hidden behind the downhill. I doubt they could have squeezed more elevation out of this course.
Wooded lines are great on the course. 2 is a tight right-finisher, 4's pin is set right behind a large tree in a very tricky spot to access, 5 has two lines to the pin through some very tight trees, and 8 is tight off the tee, leaves you with a landing zone, then back uphill there are a lot of trees to avoid on the way to the green. 6 has a ceiling to stay under off the tee, and two trees to stay between to get to the pin. Excellent hole.
Cons:
I've praised Hole 8 so much that I'll get its con out of the way, if played correctly the landing zone is on the green of Hole 1. Not sure if removing a few trees around the second corner is possible but it would alleviate this issue.
More safety issues: the tee of 2 is directly in the left line of 1, and the tee of 8 is right where a missed rhbh ace run on 7 would end up.
Hole 1 is a wide open flat nothing. And hole 7 isn't much better, but at least it's slightly downhill and the ace run is dangerous with the downhill behind the basket.
The bridges added across the creek on 2 and 8 are nice, but some dummkopf decided the one on two needed 3ft high side rails. Now, Hole 2 needs an uphill drive, so it isn't the worst thing ever, but it plays mind games with the tee shot.
From 3 to 4 is a long way. Not much that could've be done with the volleyball court in the way but still a con in any case.
Other Thoughts:
The parking area is a little small, but there are more spots up by the green of 8.
Bennett is a nice addition to an already growing disc golf area. Given proper care and adjustments it could certainly earn another half-disc to full disc from me. Definitely the best 9 in the Liberty area, and totally worth adding on to your stop at Bad Rock.
