Other Thoughts:
Course is situated in a park of about 110 acres, the second largest in the stable of Danville city parks. For a city of this size, Ballou Park is an unusually well appointed and maintained example in the English landscape tradition of parks, and the disc golf course is already very polished and playable for being so young.
The course winds around the park's north side in more or less a clockwise fashion, and is mainly sequestered from other park activities, however walking/biking trails are threaded through several holes and the nature of the park itself promotes 'wandering' from other park goers. Alertness and consideration, as usual, are good practices. Course does not feature returning 9's.
Equipment and amenities are superior, including a distance marked practice green and an ornate and very sturdy information kiosk. Creek fords are first rate and sturdy throughout. It should be noted that policing one's own refuse is required on the course. Tee pads are above average but some may feel the blue tees slightly undersized. Way finding could be a minor issue, as the only 'next tee' indicators are on the previous tee and there are several instances where adjustments to the course have left 'spare' tee pads to find. Small colored directional arrows that hang from the basket's bottoms would solve this first timers' problem quite easily. In the 5 cases of a shared tee pad, the addition of blue stripes to complement the white ones, both on the pad and sign, would also be more consistent/less confusing.
Average hole distance from the whites is about 260' with 11 holes between 200' and 275'. From the blues, the distance variability is more evenly spread, the average hole distance is 335' and only 3 holes are 480' or better. From either set of tees, there are plenty of scoring chances due to the general openness of the course, light forgiving roughs and very few ob areas. Penal rough exists on about 1/3 of the course, but reaching them requires a large mistake (usually greed) and thus your penalty is 'fair'. Ballou #2 is very forgiving of even middling mistakes overall and gets high marks for encouraging learning while retaining a challenge and for venue appropriateness. I found it very fun to play and not as taxing as some of my own local courses. It has a light-hearted, playful mood.
Ballou #2 has excellent use of elevation changes, with every type except 'over-the-hill' represented (#14?) and exhibits excellent variety as well, as the design also includes 4 essentially flat holes. Balance would be the only formal design sticking point as the course strongly favors stable counter spin shot shapes from the tee, especially the blues. Greens are generally open, unobstructed and flattish; only a few exhibit significant slopes or drop-offs and are balanced overall regarding spin receptivity.
Ballou #2 has one very exceptional hole, #16 blue, which is one of 4 'cross-the-valley' type holes here. A 480' right-to-left par 4, one is faced with the 'how aggressive can I be' question off the tee, as landing zones both before and after the creek ford are solid plays. I venture to say the hole is nearly un-pinnable from the tee, even for those with great power as the hole sits about 20' higher than the tee and both sides of the narrow fairway are bordered with some fairly penal rough (the London Plane trees here tend to soak up a disc rather than allowing penetration, but only when in leaf). 60' or so down from the pin a protective cluster of large oaks/maples will catch weak up-shots. Most golfers need to play 2 very good smart shots here to get a shot at a 3. Rollers and the 'over-the-top' approach on this hole are so risky that success with it (them) would be an anomaly. Prove me wrong and show it on YouTube.
The course's routing is very mild, with a low-key start that eases you into the more technical areas of the course. The turn is punctuated with good scoring chances and the round ends with a bittersweet difficult sequence (#15-18). Overall, Ballou #2 is a very solid effort and a course the local club can be very proud of. Should you be passing through, I strongly advise stretching your legs here.
