The Bathurst 1000 has quite the reputaion for being a calling card of unsavoury characters, it really isn't an event that caters to the family
orientated crowd.
Alcohol + Idiots = Bigger Idiots.
If people took more responsability and conducted themselves in a more appropriate manner, then there wouldn't be any need for this too happen.
They have finally shot themselves in the foot.
But you should be happy that you can take any alcohol in there at all, I seem too recall that at Phillip Island Moto GP and Sandown 500, you couldn't
take any in at all. (Though I did sneek it through past security. hehe.)
Though in saying this, when you go too Bathurst you have too expect the drunkeness and the partying.... it is an Australian motor racing event after
all.
