The game is a fairly simple one: It's like capture the flag but with a 3-pound, cork-filled leather ba. The object is to get the ba to your side of town. The trouble is that it's a no-holds barred version of capture the flag where anything goes and the players get pretty dang rough with one another.
Each year, twice a year, this Scottish town splits between the North and South (your team is chosen at birth) and plays this 400-year old game called Kirkwall Ba.
It certainly looks like a lot of fun but you'd presumably have to be pretty tough to play.
