Sorry Jaime, shouting "CAR!!" is like a secret code to "good Canadian kids", because we all - OK almost all - played road hockey as kids, complete with goalie nets and pads and orange hockey balls or tennis balls.

So you play while watching for cars. Everyone runs for the nets to get them out of the way.

"CAR!!" is usually followed quickly by "GAME ON!!"
