"I wanted to go today but the thought of paying $50 to wallow around in the mud just didn't get appealing enough."
Plus $10 carparking and the food from those take away caravan things...I'd hate to think.
There is also the big relief (bush fire/flood) concert at the MCG today. Probably grabs a few of the punters also.
Either that or some sort of conspiracy theory with Avalon becoming the second International Airport of Melbourne and the airshow becoming a dead weight to its progress?
