Amateur and Senior Opens.  He was a member of several Tri-State teams and had 9 holes-in-one and two double eagles.  Alistair was a wonderful husband and friend to many both inside and outside of the golfing community.  He invented unique and humorous names for almost everyone he knew.  He was kind, generous, witty, excellent company, and friends with people from many walks of life.  A memorial service will be held in the future and the Curran-O'Brien Funeral Home is handling all arrangements.
