Pros:
...either way, the Rocks aren't really that noticeable here in Lancaster, Ohio, but the disc golf course is really wonderful! A popular course that gets a lot of play, Flat Rocks has something to challenge all levels. If they wanted to set the baskets in all the shortest positions, it would total 4894 feet: a fun Recreational level layout. If they set them all as long as possible, and you play all long tees, the course can muster up 7538 feet: enough to challenge Advanced and Open players.
The course features shot shaping in both directions, excellent use of elevation, woods, and gorgeously mown tall grass, rolling fields (see pictures for a tease). Amenities include really long, narrow, well-maintained rubber (short course: "Flat Rocks") tee pads and similarly sized, flipped carpet (long course: "Hard Rocks") tee pads. Signage is fantastic at the short tees, including map, distance, obstacles, alternate basket positions, and other details, all protected in an aluminum frame. Really classy. The long tees have simpler posts indicating distance and hole number. Baskets are top quality Chainstars with the orange logo on the center post for increased visibility.
They've added benches, and (leave it to folks likely to have a little hunting in their backgrounds) two climbing stands behind the teeboxes on holes 4 & 8, where a spotter can get up and see over the blind rise to track a partner's tee shot. There's a practice basket right by the parking area, course kiosk/ info sign (with scorecards), port-o-let, and at least four picnic tables in the shade of a group of mature trees. For the most part, the course flow is intuitive, and does feature two loops of nine holes.
Memorable holes abound, from the hard bending 1st and 16th (long), to the run into the woods on 2, the long downhill glide on 9, the views across the smartly mown grassy lanes on 11, another tough turn into the woods on 13, all the way to the incredibly tough line required on 17 long, and another downhill finish on 18.
Cons:
The only issue I had was as a traveling player getting used to some of the transitions. After 5 (in the longer, 'B' position), you need to double back left, and not go forward down the path, even though there appears to be a path sign down the hill to your right. It's really confusing after hole 12, as the tees for 13 and 17 somewhat overlap towards the woods line, and after finishing 18, the natural tendency is to wander back to the left, where you'll be crossing the 10th fairway and the 9th green (I assume there's a more direct path in the woods to the parking lot). I would guess that, if the folks doing such a good job here with course upkeep and improvements visualized playing it for the first time, they'd spot the areas that need improved 'next tee' signage.
Other Thoughts:
When you drive in, look for the sign for Keller-Kim nature park at the 2nd drive (Bogear Circle is one way, counterclockwise). Finally, when I first started playing, I committed myself to giving courses multiple looks before considering writing a review, so it's actually been a few years between plays for me here. But if I were road-tripping to the area around Pickerington and Lancaster, Ohio, I'd make time to play Simsbury and Flat Rocks again and again!
