Well... several years ago (not too long after I had taken the game back up after not playing since my teens), I had a 6 hole playing lesson with my instructor, with her acting as my caddy, that is, clubbing me and providing the course management. At this time, my best 18 hole round was a nifty 108. On this day I was 2 under for the 6 holes. Sooooo.... maybe he's not so far off.
