Those guys are brave. Trust me, crocs have an AMAZING stealth when they are in water, especially when near "food". I wouldn't be getting that close to the bank if there are crocs about! I visited a tropical zone in my state, called "Cairnes" (its in Northern Australia). All the waterways had warnings along the lines of "DON'T SWIM IN ERE YA CUNT! Crocs are fucking EVERYWHERE! STAY AWAY FROM THE WATER, YOU BUNCH OF DAFT, DRUNKEN PRICKS! By the way, got some smokes bruh?". Such warning signs pepper northern QLD and the Northern Territory. In fact, the capital city of Northern Territory, where stupid people ignore the signs and get attacked EVERY YEAR, is literally named "DARWIN".
