At one time, in the early days, ANGC had quite a few centerline bunkers, namely at #2, #8, #9, #11, and the infamous monster at #14.
Ross used centerline bunkers, even if the infamous top shot bunkers are not considered. Seminole #16, #18 on the plans anyway, Holston Hills #5 and #12, etc., etc.
I think 'they' used centerline bunkers.
Another question might be....How many centerline bunkers were removed ?
