There were a good number of posts about it, but it was a long time ago, and I don't think they are in the archives.
My recollection is that it was an inherited routing that C&C couldn't alter much, if at all, due to permitting issues. I believe Tom Paul is one of the few people on here to post somewhat extensively about the course; perhaps he will see the thread and chime in.
I'll dig a bit in the archives and see if I can find anything.
