Here's a video clip showing a unique way to cross a flooded river.
The vehicle clearly has either front- or four-wheel-drive, so that even when the rear floats, the front wheels can still move it; and the air intake is raised to roof height, which prevents the engine from cutting out. Even so, that was a pretty risky maneuver. If the water had been just a bit higher, vehicle and occupants would have been swept downstream . . . and who knows what might have happened then?
Still, the boys seem to have enjoyed themselves. I'm surprised they didn't begin by shouting out of the window, "Hey - hold my beer and watch this!"
