Ran and Jeff,
That is what I heard as well - basically moving the bunkers back to the pros landing areas of the day, but not necessarily the exact same pattern.
I'm not sure that I haven't seen the plan myself. Once, on a flight into Detroit, I stopped by the maintenacne building to ask permssion to tour the course. I had called ahead but got no answer. When I got there, it was open, but still no one there. There were a stack of old plans, including some by Ross and RTJ on a table, which I looked at liesurely, hoping the superintendent would come back and escort me on the course.
I hate to admit it, but I was tempted - for probably the only time in my life, even for a second! - to steal something! My conscience prevailed, however. My plan collection did not!
