Dave:
What I suggest for that extra round is to play your favorite course one more time, but all the way back, and see how good your short game is on all the greens you can't reach and the difference in your score and how different the course plays.
Another fun thing to do, is to play the course with only 4 clubs, and see how you do. You have to manufacture alot of shots that way and it is a hoot to do it with a group of relatively good players, shows how versatile you game is.
Lots of fun,
Cary
