Bugs will stop me. Also someone down the fairway who walks into my field of vision that I did not know was there will get my attention. Golf balls at horn honkers. I can understand it, but it can cause a load of problems. A golfer did that on I-40 in Kingman AZ. The ball hit someone's windshield, contributed/caused a multi car pile up. The golfer stayed on the course. He was in a group in front of us when we saw the wreck, but did not know how it happened. About 30 minutes later the AHP drove on to the course, and arrested the culprit. He hit a car, but it was semi truck rig that honk his horn in the middle of his swing. The semi never stopped or probably ever knew what happened.
