A runner filmed a face-off with a large bear that pursued him for several minutes in Grand Teton national park in Wyoming, producing a three-minute video that went viral. Evan Matthews said he often saw bears on his runs, but none had dared to come so close. ‘This one was interested in me, so I had to change its mind,’ he wrote. Rather than use his bear spray, Matthews opted to reason with his ursine inquisitor.
