You can see a number of the infamous fill pads at Fishers though the fairways are probably not watered. Fishers has a few but probably not as many fill pads as many Raynors. Anything Raynor always strikes me as the opposite of natural and the holes are always fun to play.
Dunaverty in my only play, long ago, seemed very natural.
Many of the older public courses in East Tennessee are very natural, they just didn't move much dirt, and bunkering was very very minimal. Had more to do with budget than anything else I guess and having to move clay as well. When I played a lot of those, clover lies were some of the best.
