Pros:
This course dates back to the 'Steady' Ed Headrick days of the development of the sport, and is therefore appropriately scaled for the casual to recreational player of today. All nine holes are between 210 and 278 feet, but make excellent use of the elevation and the trees left in the clearing of the 600x600 space they had to work with.
When the foliage is thick in the summer, there are clearly intended flight paths including hyzers, annies, and S-shots, but none of the baskets are much uphill from the tees. Most of the time, the hills are in the fairway, and make for a decent mini workout as you play. I say mini, as I'm a fairly big guy, and appreciate being able to work on my conditioning in small doses like this.
Holes 1, 2 & 3 work back and forth down across the first slope, then the (feature?) 4th hole bends right around a summertime blind (foliage) steep valley. #5 seems longer than it really is (for me) because I worry too much about the thick and thorny bushes to the right of the fairway. 6, 7 & 8 go back and forth across the lowland coming back to the parking lot to finish on 9. #7 can punish an errant drive because the fairway narrows at the end between some substantial bushes.
The park has the usual shelters, bathrooms, and a water fountain across the drive, and soccer, volleyball, and a newer kids playground nearby, so there are activities for the family. I've seen a shuttered concession stand, but I'm not sure when/if its opened. The course has plenty of trash cans, and a couple of benches at the start. There is a good course sign with a map, but the only tee signs are the 'medallion' style plaques on the ground by the asphalt tees (not concrete, as the course home page says).
The maintenance is good, as they mow the fairways regularly, and keep the rough (longer grasses and clover: watch out for the plethora of bees in the summer if you're sensitive to them) in fairly good shape, so you don't lose a disc often. They recently marked off dangerous fallen branches after a storm, and clear them as soon as they can.
The course has never been crowded when I've been there.
Cons:
My top complaint (aside from the fact that they used asphalt pads around the baskets in Hamilton County parks) is that the baskets are really old and inconsistent. Single chains combine with weak, shallow baskets and variable heights (including variations in the 'drop' between the chains and the basket) to rob you of some decent shots. Some go through, some (including what should have been my first ace) simply bounce out. Not important, but the second basket has a plate that says '9'.
The asphalt tees are becoming very worn and cracked.
It is possible to get over into the parallel fairways, which could be a problem if ever crowded.
Other Thoughts:
Hamilton county park passes are $3/day, but only $10/year with coupons and access to all the parks, including several area DG courses.
Edit 9/15/14: Though the parks department continues to maintain the grasses and the edges of the shrubbery pretty well, the Emerald Ash Borer and other tree issues has meant removal of at least a half dozen of the trees that formerly limited your lines of flight. So a tight little course has become more open. If folks actually played it, it might be a little more dangerous in the past year or so. They even cut out the shrubs between the 7th basket and the 8th tee, so the latter is in play for the tee shot from 7. But I think folks don't play it much because the tee pads and baskets are incredibly dilapidated. Had to realistically drop a half rating point as a result.
