Can a golf hole be "fun" if you've only played it one time? Can a golf hole be fun, independent of your score on it? I've never played Oakmont, yet can vouch for Kevin's respect for the course. I imagine that a person's definition of fun depends on the tilt of his life's axis. Fun for some is a goofball, new-age hole like Fossil Trace, while another one finds fun in a Raynor or a Flynn or a Travis.
I've yet to play a course that didn't have a "fun" hole on it. Unlike some on this thread, a fun hole for me can be of any distance. It usually involves heaving, rolling land; some element of uncertainty/blindness; the ability to fashion a bounding, ground ball around a hazard; a monumental, hold-your-breath carry or a massive, undulating green.
As a mid-low handicap (not scratch, but not a seven), Ballyhack was unbelievable fun for me...I loved the rugged features of the course, yet didn't like the short par four 6th...not the one time I played it. Had I played it over and over, I would have figured that cape hole out and probably come to hit a reckless driver and sent caution to the wind. The 9th at Kinloch, same architect and completely different feel, could also be a fun hole, once I figured out how to play it (and developed enough confidence in my fairway metal to get the ball over the hazard on the second shot.) Huge green that I 3-whacked for bogey, crazy yet fun.
and those are two of many...
