Pros:
There's no chance of a lost disc at this rolling, established park, where the nine hole disc golf course boasts dual tees and nice DGA baskets with number plates. The concrete tees each are nicely marked at the front with either blue (long) or red (short) paint, so that you'll always know which direction to look for the basket, regardless of the orientation of the excellent signage. In fact, the flow of the course is enhanced at the only long walk (7 to 8) by a next tee sign for first timers. With a paved walking trail, a separate, fenced baseball diamond, a couple of playground areas, and a small shelter, the disc golf course takes center stage, and you can always see clearly to watch out for conflicts.
The disc golf play is geared toward Recreational distances from the 'amateur' tees, and probably Intermediate distances from the 'pro' tees. There are mature trees and gnarly branches waiting to swat down your errant drives (particularly on holes 3, 4, 6 short, 7, 8 and 9), so it's not all 'grip it and rip' it here. That's not to say that the lines are tight, they'll just take a little planning, and sometimes conceding a three (or four), rather than an easy deuce. The signature hole might be hole 8, with it's daunting trees guarding the ridge top green.
Park maintenance seems to be pretty good here, and the course has been in good shape the two times I've visited, over a span of two years.
Cons:
There isn't a lot here to challenge the tournament player, and interest would quickly wane if you are at that level, and live in Danville. Might have to play some safari. I do already worry a little about the proximity of some tees to the previous basket (long tees for 3 & 4 in particular). And the approach to the 3rd basket definitely brings the little shelter and swingset into possible range of the bigger (wilder?) arms. Finally, roll into the gravel lot slowly, it's a little worn-down.
Other Thoughts:
I added some new pictures and an aerial map so you can get the flavor. Not necessarily a destination course by any stretch, but a decent place for the folks in this small college town to get some play in.
