Adam,
You are thinking of Ridgemoor. I get my Moore's mixed up all the time.
Looks like Edward Lawrence Packard added the other nine holes in the mid-60s.
Shivas,
That's the answer to why this is the Pat Mucci edition. I left a few of Bob O'links holes in the current aerial in the upper left hand corner.
Ross designed Bob O'Link a couple of years before Northmoor was built. Pat started a thread recently about how modern architects don't design courses next to one another like they did in the Golden Age. Among the reasons cited as to why this no longer occurs were market factors such as not wanting two courses by the same architect to compete with one another for members or status. This made me question if the proximity of another Ross course so close to Bob O'Link was a factor in their decision to have Colt/Alison completely redo Bob O'link in the 20's.
