Baxk in the early 70's, during a local golf tournament, my brother set the course record at DCC. I don't know if his 63 has been bested since, but I can't believe anyone has beaten his front 9 of 27.
He made a double-eagle, 2 eagles & two birdies. Imagine, 9 under with 4 pars! And that was after the first 5 holes! He also only hit 2 fairways. He played much better on the back 9, hitting every fairway & green & could only manage one birdie. His bogey came on #10 when he took a penalty shot on the tee because he WHIFFED his drive from nerves after the front 9.
A wonderful round & great score made in as bizarre a fashion as any ever.
