While not a Maxwell classic, my Sand Creek Station is also on Highway 50, near I-35 in Newton, KS and on the way there or back. A friend of mine just played PD and SCS on the same day. SCS is the third ranked public course in Kansas and has some architectural homages like the Road Hole Green, Alps, Redan, etc. Held the 2015 Publinx.
As noted, Dornick Hills is nice and I stopped there on my way back from Tulsa a few years ago. The members redid the greens in the 1950;s, hired my old boss to do the front nine, then hired us to match Nugent rather than Maxwell on the back nine. We discussed restoration, but they had no budget and didn't want to do that at that time.
Still worth a play. When I was there, CCA had taken over management, but I think it is still a members owned club.
