Curling? I know little about it myself. It’s a game sort of like shuffleboard, that is played on ice. You shove these round, smooth “rocks,” about a foot in diameter and half a foot high, if memory serves, down a lane and try to put them in the right spot. Someone else runs along side the rock as it travels down the lane, sweeping in front of the rock, when desired, to guide it. There are two teams of two (I think), and they each get to throw several rocks. Not only do you try to put your rock in the right place, but you try to hit your opponents’ rocks and move them into the wrong places. I think the rocks have handles on them.
