During practice, members of the Worcester Hurling Club hit a sliotar (ball) with their hurleys (stick). That's Worcester, Massachusetts, not England.
Hurling is a 14th century sport resembling field hockey that remains popular in Ireland. The club's founder, Dan Donahue, learned the sport while studying abroad in Dublin. Points are given by getting the sliotar between the goal posts or in the net, which is guarded by a goalie. One point is awarded if the sliotar passes through the posts, three points if the sliotar makes it into the net.
The club received help from the Boston-based Gaelic Athletic Association and the Irish Government.
Along with mundane clubs, hurling is occasionally played in the SCA.
