Sven--
Thanks for posting reply #1305. Very interesting to me because that raw land on the other side of the Snake River shown in the photo is the pioneer fruit orchard that became my course, Canyon Springs GC. We roamed this canyon as kids, not much spoiling our love of this wild landscape by playing golf. When my father built his own 9-holer in 1972-4 (I helped some), the plan was to add it as the second nine for BLCC, a plan eventually rejected by the membership. Instead, they used his "first-course" architect, Max Mueller, to build their second nine (Max's office was in our maintenance shed). Ten years or so later, my father built his second nine.
I haven't read enough of this thread to know how people use it. However, perhaps for the first time in the many years I've been on this site, finally there is a post about a topic that I am probably the definitive expert source. I was born in 1949, the year BLCC opened for play, and have been intimately associated with these properties for 70 years. If anyone wants to know anything about these courses, I'm your huckleberry. The routing map posted, for example, is remarkably accurate to what was built.
I showed Tom D. around both these courses a few years ago and his reviews are in his CG, vol 3.
