Pros:
18 holes consisting of nice level turf tees, bright lime-green Prodigy baskets, and informative tee signs. Good variety mixing of pars and hole distances and fairway shaping for advanced-pro level players. Mostly tight well defined fairways and steep elevation changes which are the main features of this course. Strong club presence and love with the rough surprisingly well maintained, not much underbrush or thorny stuff off the fairways.
Cons:
Basically one big loop - long 14 hole loop and short 4 hole loop back to parking lot. Long walk between 13, 14 and 15. No alternate tees or basket positions, brutal course for novice players. Navigation was tricky in a couple places, bring a map. Hole 1 plays down a walking path and hole 18 plays along a park road. Moderate chance to lose a disc in places. Some very steep and dangerous terrain in places. I don't recall any restrooms or portapotties.
Things that may vary/change - Wasn't the cleanest and quietest course, it plays along train tracks, and I saw a junked washing machine among other litter. The mosquitoes were absolutely atrocious, I had a cloud of them following me the entire round even fully soaked in deet. I had my first encounter ever with a skunk here on hole 6, I almost stepped on Pepe Le Pew and he growled at me while I was searching for my drive, luckily he didn't spray.
Other Thoughts:
Starting off my GPS took me the baseball field parking lot, I asked the county cop sitting in the lot if he knew where the disc golf was and we were looking at the dg course map I had and figured out it was just across the foot bridge. So after finding hole 1 it took me even longer to find hole 2, go uphill pass basket 14 and go right down the park road. Hiking uphill on the sand dune with basket #4 perched on top it on was hell, this was also my last course on my 5 day road trip so my legs were already beat.
Hole 6 is probably the signature hole here, and standing on the tee I really liked what I saw, but hidden beneath the beauty is a very small landing area straight ahead, the left side slope next to the train tacks is extremely steep and loose ground and hard to traverse and harder to throw a standstill shot without tumbling, the right side off the fairway has more rough and trees and makes you play further uphill, I imagine there will be more many more 6s than 3s on this par 4, probably plays closer to a par 5.
I really liked hole 8 which is a par 3 421' downhill hyzer. Hole 11 was a fun par 4. Hole 17 was fun and unique, short downhill touch putter shot to an elevated island. Hole 18 is a tough long par 4 and the only hole that may resemble open or flat, it plays down the park road as OB left and the basket is basically situated on a tiny island.
Overall I have some mixed love-hate feelings about Rockwell, there are some really cool holes here, but as a traveling player playing here for the first time, it kind of felt more like work than play with the amount of time spent on navigation issues and searching for discs, and the amount of hiking involved, and the mosquitoes constantly buzzing me. I'd recommend this course to in-shape intermediate and above level players, and travelers with the caveat to allot for some extra time.
