Pros:
(William) Harbin Park features a longish disc golf course north of the Cincinnati outer belt, which runs uphill near a huge water tower, and incorporates a gigantic sledding hill for its occasional temporary holes (played often in a few of the area's prestigious tournaments, like the Flying Pig). I like hole A which allows for a huge downhill bomb to a ridge near the bottom. If you have a portable basket, it's almost worth dragging it out to watch your best stuff glide down there.
The fairways are usually well maintained, and each hole has a good-sized concrete teepad, decent sign and waste receptacle. The park has several shelters, including one with a huge stone fireplace we used for our true Ice Bowl this year. Most other activities occur in the other areas of the park, and a walk/jog path doesn't come into play, unless you really get off track.
The course can be a little intimidating for weaker arms, as it opens out with three uphill shots, followed by a monster 725 footer that finishes near the high point and flagpole at the 'top' of the park.
There are a handful of birdie holes (better players might call them ace runs) to make up for the tougher ones.
The holes flow nicely back to the starting area after nine, and loop to the left side of the park for the back nine.
Harbin incorporates its natural elevation on most every hole, and requires turning drives in each direction, though it's a very open course.
Cons:
There are no benches near the tees, the 6 uphill shots tend to feel a lot alike because of the lack of trees/foliage, and at least one of the teepads (#1) has an uncomfortable upslope.
The rough can get quite long, causing surprising difficulty in finding an errant disc (it feels weird to search for more than a minute when you're really just looking in an open field!).
Can get very muddy on the back nine (#14 can be a swamp, as can the passage through the bushes after you finish #18).
Other Thoughts:
Harbin is a challenge for novice to recreational players, but its length (relative length, including the uphills) appeals to intermediates and above.
If you're only in the area for a while, I'm sorry, because there are more than a dozen worthwhile courses here, and you might not have time to try them all. But Harbin falls into the worthwhile group, so come on back if you haven't partaken.
