A friends dad lived right behind the 14th flag on a course just north of us. He lost a few windows that the course replaced no issues. The best of this was he would gather up all the balls that the boys left in the yard and my buddy and I had bleasst sending them back out on the course at will. Nt to harm but man it sure did screw with the players,If you live that close to a course, that is probably bound to happen. Might be worth looking at something shatterproof.
