Wind likely does enough without adding me losing a 9i that slipped out of my hand due to wet conditions. I would then have to go back to the pro shop and spend more credits on another club....and a glove, umbrella, towels, etc.
But, sarcasm aside, I LOVE the idea of adding more weather elements....if it were only possible. However, if it made you go back and spend the resources to reshoot a course, I would rather you use those same resources by adding a new course.
