Spring Valley, near Salem WI (tucked into the SE corner of the state, right across the Illinois border near Antioch IL) is an original Langord/Moreau course that is bunkerless. A very good course, with a terrific set of greens that are kept at a very challenging speed (faster than Lawsonia has been keeping their Langford/Moreau greens in recent years). GCA regular Dan Moore has dug up some research on Spring Valley, and the modest course -- public, and very low-key -- filled in its bunkers, presumably as a cost-saving measure, around the time of WW II (or perhaps near-post-Depression), I believe. It plays @ 5,900 from the whites and @ 6,300 from the tips, and its lack of bunkers takes some of the teeth out of the course. But not a whole lot -- typical of a L/M course, its challenges come from the greens and green surrounds (pushed-up greens, sharp falloffs, both bold and subtle green contours), and those provide some good challenges, bunkers or not.
Interestingly, another intact Langord/Moreau course in Kankakee, Ill., affiliated with a local Elks Lodge there, appears to be bunkerless, or to have very few of them left, based on some aerials I've seen. I have not played the course, although it may be part of a Cheesehead/Flatlander Langford/Moreau tour in '07...
Sean -- those pictures of Kington are just neat as can be. Looks like really enjoyaable stuff.
