It looks like there's a new 9 installed in the last year, incorporating the other half of the park. Most holes have 2 tees (with nice signs on the longs). Overall, it's a fun play but fairly open. You'll have plenty of downhill long shots to watch your disc soar. Here are my highlights:
-Maintenance is excellent. Short grass, no rough.
-Nice DGA baskets
-Maximized the land available (this a ball golf course once upon a time?)
-A few holes perched on the top of mounds and one cleverly built 4 ft high into a tree stump
-Hole 8 uses the trees and a ridge very well to create a really nice low-ceiling dogleg left to a tough basket position.
-Most holes have some character and require some kind of shot-shaping to score well

Foremost, the issue here is the safety of the layout. Tees are close to baskets and there are many cases where your drive could impact other park users and disc golfers. I was fortunate to be the only guy out here today. On at least 6 or 7 holes, you'll have to worry about anyone standing on the next tee in front of you. It gets really sketchy on hole 12. There's a blind landing for hole 12 near 13's basket. And once to you get to 13's tee, you'll be throwing right past the putting/approach area for 12. The drive on 17 is completely blind and winds through the walking path. 18 was a beautiful hole, but on my upshot, I worried about potentially decapitating a runner or cyclist cresting the hill on the path that's right next to the basket. Outside of the safety issues, my problem with with the course was the overall openness. With the space available, the designers did a great job but squeezing in 18 holes was a tall task.

If this park was solely meant for disc golf with some safety measures, I'd imagine a 3.0 rating. Thankfully I was around when no one was there and able to air it out and enjoy the experience. This is worth stopping by if you're in the Danville area. You won't be far from the solid Riney B and Eubank courses.
