To me, anything that would promote the construction of more par-2 courses would be worth the effort. Let's face it: golf takes up too much time. Nine-hole courses and par-3 courses, if more widely available, would seem to provide a solution to the six-hour golf experience (drive, warm up, play, eat and drive home) that is driving down the number of rounds played every year.
How about a separate listing for best nine-holers and one for best par-3 courses? More lists means more courses get more credit and the consumer gets more information.
