I don't know how long they've been adding short courses to places, but since I'm 54 years old, that's the number I choose.
My first short course was the Audubon par 3 layout, on Maple Road, Amherst, NY. It's a terrible little pitch and putt. My next one was the short course at Turning Stone. Much better.
Public, private, bring them all in. Any country on the earth. Don't feel restricted by hole number on the card. A great hole is a great hole. Multiple holes from the same course/designer allowed.
