Regarding the goanna, I nearly got run over by one in towards the chooksville track. I hit the prone position quickly because he was eyeing me up as a convenient tree stump to climb and you know what their claws are like.@Cervus elaphas
That's why I keep a piss bottle in the tent.
If you want to see the shit hit the fan, throw a goanna into ya mates tent and zip it up. Stand back and watch the comedy show and see if you can still stand while laughing your guts out.
