Holes, stretches, entire courses: whaddya got?
For the pedants:
easy and interesting adj Wherein bogey or better is a reasonable expectation for nearly all golf skill levels, par or better is a reasonable expectation for handicaps 13 and lower, yet play is far from boring; additionally, losing one's ball is impossible or nearly so and forced carries, 3-putts and other signposts of difficulty are almost always absent. Possibly: the golfer's ardor to play the hole / stretch / course increases with familiarity or repeated experience.
