wow that really was a close encounter
My mates dad told me that when he was young he was out on his quad bike and he saw this king brown or eastern brown cant really remember but it was some sorta brown snake..anyways he said he sped of as quick as the quad bike could go and this massive king brown or whatever it was chased him and was keeping up with him even though the quad bike was goin full bull..

not sure if it was true or not but he's the type of guy he doesnt pull your leg about that sorta stuff
cheers gurds
