Affectionately known as Croker, this is a Gaelic games stadium and they plan on keeping it that way. What that means is that if you're in Dublin, you should catch a Sunday Match at Croker and bear witness to one of the most savage, incredible sports in the world, hurling. Think lacrosse played with giant field hockey sticks with a healthy dose of rugby thrown in. No pads. So awesome. (Seriously, these dudes are crazier than those Skull and Bones fuckers.)
