Lots of fun,social things happen in Ireland on St Patrick's day and Stoneballs Company have found a cracker of a link to blog about!
Bol Chumann na hEireann or Irish Road Bowling!

The balls were originally made from stone - if anyone would like to use stone balls you know where to come. We're all for preserving past traditions.
Quite simple really. But the best things usually are.
Have a look at the video to see road bowling in action. Olympic sport?
