Dan:
I had thought Culver was relatively open; that one picture threw me for a loop. Perhaps reminiscent of West Bend's front nine, where parts of 6, all of 7 and 8, and the tee of 9 are carved from an old-growth forest. Spring Valley's 15th and 5/16 tees are similarly situated.
Does Culver have the land available? Probably not the money, although that place has some well-heeled alums.
