When a player gains one or more Fans, they must place them on any space at least one Track Piece ahead of them, so long as the space doesn't have an object or Racer on it. Fans cannot be placed on the Finish Line itself, but may be placed on the Finish Line Track Piece. If a Racer cannot place Fans normally (due to lack of space, for example), they may place the Fan(s) anywhere on the Track.
If a Fan is discarded from a game effect, the Fan is removed from anywhere on the Track (unless the game effect states otherwise). If a Racer has no Fans, the discard effect is ignored.
