Spectators can make or break a sports game.
I love the comments that wits in a crowd hurl at hapless players or woeful referees. When the four-letter words are kept to a minimum and the comments are bang-on, some spectators are better than any of the paid commentators.
But when you get the foul-mouthed, abusive couch potatoes sitting sideline, it makes for a gruesome experience.
I don't like the booing of the kickers in rugby that seems to be a relatively recent phenomenon and I'll never forget that image from North and South magazine of a young Canterbury rugby fan, sitting next to his dad, holding up a sign that read "I hate Auckland". That kind of ugliness doesn't belong anywhere near a sports field.
I'm right behind the Herald on Sunday's campaign to clean up the sidelines - especially in children's sport.
