Reviving a very old thread here because the geometric feature question got me thinking about Butterfield. I knew that it was originally a Langford course, but the features were definitely gone or hidden in the trees before the Smyers renovation. And after the renovation, I don't think that anybody would say that it has Langford features either.
I went back to find the historical aerial to see what the original version looked like, and I am surprised by it in a few ways. First of all, the routing is exactly the same as far as I can tell. The holes that currently have forested areas that affect play seemed to also have mature trees in similar areas in the original. On such a big property with 27 holes and so much water, I would have expected things to have been rearranged over the years. And it really is a great routing, so I'm glad to see that Langford's work is preserved in that respect.
The biggest surprise though, was the bunkering in the original. Specifically the grass islands in the traps. I haven't counted, but there must be over 40 of them. The bunkering looked very unique. Was there any other instance were L&M had bunkering like this?
