I am no longer in croc country but every time I was in a tinnie in a croc country i always had the one thought.
"if only these big buggers were just a teeny bit smarter they would jump onto the side of the tinnie and swamp us.... all you can eat smorgasbord"
Crocs are cunning.... they lay in shallow water on the bottom and stir the mud with their tails deliberately so they can hide in bugger all depth. They watch for patterns at the waterside and lay in wait for a repeat episode. It's always seemed to me that it wouldn't take much for them to learn the side swamping technique.
If they did that then a whole lot of boats would become unusable in northern Australia. Silly thought perhaps.... but all these tourist tours teaching crocs to jump for chicken legs can't be a good thing in my book.
