Pat:
Dan Moore is the resident GCA in-house expert on all things Langford.
From what I know, Lawsonia probably comes as close as any Langford-Moreau designed-built course to the original plans and design of an L/M course. That is, if you wanted to show a novice golf architect nut the epitome of a Langford/Moreau course, you should take them to Lawsonia. Dan's definitive thread:
http://www.golfclubatlas.com/forum/index.php/topic,37022.0.htmlThere have been a few changes here and there (Dan mentioned in a previous thread that Ron Forse indicated the 14th green had been rebuilt; the opening par 4 1st hole at one time was likely a par 5 with a tee near the current putting green; several sand bunkers original to the course are now mounds, such as the one on the par 4 8th hole), but I'm guessing about 90-95 percent of what you see at Lawsonia is the original course as intended (with Forse playing a pretty key role at one point in "restoring" the original vision of the course through some tree-cutting and other enhancements).
Spring Valley is an interesting case study, in that the owners there know what they have in terms of an original Langford (the architect's final drawing for the course is hung handsomely in the modest clubhouse), and little has apparently been done to the course over the years. It's rough around the edges, no doubt, but that's part of its charm, and it would be really neat to see the course with all the bunkers originally planned for the course filled in. I think the biggest issue with Spring Valley, after repeated visits, is that the original greens have shrunk considerably over the years; you could expand nearly every green out there to "fill out" the green pads as Langford designed them. Still, the Spring Valley you play today is -- educated guess here -- probably little changed in the past 50 years or so. (I've been taking pictures of Spring Valley for several years now, and my goal before the snow flies this year is to post a hole-by-hole thread on the course.)
Ozaukaee, in the northern Milwaukee suburbs, has a ton of intact Langford over some interesting terrain, with a great set of Langford greens. But there is some distinctly un-Langford-like mounding and sand traps out there due to 1970s-era renovation work. Worth playing for the greens alone:
http://www.golfclubatlas.com/forum/index.php/topic,44430.0.htmlSome on the GCA board have played the Kankakee Elks course, which has significant original Langford left. But it's said to be overly treed in several spots:
http://www.golfclubatlas.com/forum/index.php/topic,30665.0.htmlThe "Heritage" course now associated with Greywalls up in the U.P. of Michigan is an original Langford nine, but not sure how much of his original work remains; hard to tell from these pictures, but I know some on the GCA board have played it:
http://marquettegolfclub.com/gallery_heritage/Wakonda, in Des Moines, is said to be routed over some great terrain, but I've never gotten down there to play it.
Skokie, of course, has some trademark Langford features, but it'd be a stretch to call it a true Langford, as that course is the work of several architects, including Ross:
http://www.golfclubatlas.com/courses-by-country/usa/skokie-country-club-il-usa/The original nine holes of Langford at Harrison Hills are said to be extremely well-preserved L/M:
http://www.golfclubatlas.com/courses-by-country/usa/harrison-hills-in-usa/I've also played the original front nine at West Bend CC northwest of Milwaukee, a terrific set of holes by L/M over some very good terrain, with some tweaking over the years. Probably over-treed in some cases, but the architectural bones there are terrific.
Others of note:
-- Tom Doak was looking for courses in Arkansas to study for possible inclusion in the updated Confidential Guide, and some of us recommended Texarkana CC, done by Langford and Moreau in 1927.
-- As noted in Neil's post, L/M did a lot of work in Illinois and Indiana (and more generally in the Midwest), but I've gotten the impression (esp. with his work in Illinois) that much of their work in these parts has been significantly altered. A lot of L/M courses in the Midwest are NLE, largely due to post-WWII expansion of housing and development.
-- He did several courses in Florida, but most are NLE; Wexler's "Missing Links" devotes a few pages to Key West, which looked like a really neat design.
-- Dan has also mentioned that, post-Depression, the L/M firm did lots of small and relatively modest projects, sometimes perhaps without attribution, as a way to simply pay the bills when golf course construction took a dive. One such course is said to be here in Wisconsin, and it certainly has some characteristic L/M elements, but I haven't been able to verify it (yet...) as an L/M course.
