I love my grandmother dearly, and she is a highly intelligent woman (achieving high marks while earning her degree from the University of Minnesota during the depression).
That being said, she has a poor grasp of the modern American vernacular, and as such she misses the subtle humors and plot devices of many artistic endeavors. Hence, I would be bored to death by any book, movie or golf course that was simplified enough that she would comprehend every important aspect of its design.
Isn't the greatness of TOC imparted by the infinite subtleties that make every round there a learning experience? If grandma gets the whole message after one play, I'll just have her relay the gist of her experience to me and save myself the substantial greens fee.
