Man lost in swamp survives on urine, stems

 Louisiana - The 65-year-old head of a university in Colombia says that he ate a few plant stems and drank urine to survive four days stranded in a Louisiana swamp. Francisco Piedrahita of Universidad Icesi in Cali, was spotted from a Sheriff’s Office helicopter in a clearing several hundred yards from the trail where he had to photograph brightly colored male wood ducks. He left the end of Wood Duck Trail in search of a pond that he later learned had dried up, he said. The walk in the park “looked like no risk at all” but he was worried about losing his mobile phone, so he had left it in the safe at his hotel, he said. He tried to make his way back to the trail but soon found himself in a swamp.  More
