Spring Valley GC, an original and largely untouched Langford/Moreau west of Kenosha WI, just north of Antioch IL on the Wisconsin/Illinois border. Discussed on occasion here by us Langford nuts, it's completely bunkerless, features some terrific greens, and a wonderful set of par 3s. About as low-key as it gets; maintenance is OK, pace of play uncertain, but a neat museum piece. At an all-day weekend rate of $21.50, maybe the best under-$25 course in the Midwest.
