Who is responsible for damage caused by golf ball on a public course if it hits a window on a house?

The person who hit the golf ball would be liable, since he or she was the one who did the damage. And the golf course would also be liable, since it was one of its invitees, doing the activity that the golf course invited them to do, that did the damage. The homeowner would have the option of pressing a claim against either, though since the golf course is larger, presumably has insurance, and is easily identified, they'd be the logical choice.
