At Prospect, a Rooster crows after the home team kicks a goal.
At Noarlunga, a Panther snarls after the home team kicks a goal.
I guess it's hard to capture the noise of an excited Redleg.  So what happens at Norwood when the home team kicks a goal?

That's right - they turn a green strobe light on to the hill.
Not entirely sure what this is supposed to achieve.  Is this some way of pre-empting violence on Coopers' Hill?  Give the troublemakers a seizure before they can start swinging fists?
Seriously Norwood:  Not Cool.  May the Redlegs be held goalless in every game henceforth.
