I just saw this story on the AP wires: . Yowza.
The boaters – two Americans and a South African – traveled some 1,000 miles of river this way, through some of the densest concentrations of man-killing wildlife in the world. They were on a quiet stretch of the Lukuga River in Congo, paddling just 4 or 5 feet apart, when a crocodile slipped up from behind and ripped trip leader Hendri Coetzee from his red plastic boat.
This crew certainly knew what they were doing and what the risks were, but this is why nature must be respected.
