The kind that's played on ice, not "field hockey". Saw a picture of two members of Ireland's hockey team in yesterday's Irish Independent. I hope they do well, but the fact that there's no rink to play on must surely be a bit of a drawback.
I remember reading a few years ago that Owen Nolan best Irish-born hockey player told the Taoiseach that anytime Ireland wanted to win a medal at the Olympic Games that he could put together a medal winner full of Irish-Americans and Irish-Canadians. For whatever reason, hockey is the most "Irish" sport in N. America.
