A search and rescue call in Kelowna's Boulderfields area turned out to be a lone camper singing to himself in the woods. His music of choice? Canadian rock group Nickelback.
Two hikers had contacted 911 after hearing what sounded like “repeated cries.” The crew immediately switched from training to rescue mode, activating its drone team along with two RCMP officers.
The first members of the crew who arrived at the Boulderfields could hear “faint yelling – but couldn’t make out what was being said,”
...The camper was “singing his heart out to the trees, blissfully unaware that the acoustics of the Boulderfields had turned his tent-side concert into an accidental distress signal,” according to the team.
“He wasn’t in trouble,” said search manager Duane Tresnich. “Unless you count his singing.”
