Close Encounter With a Bear Caught on Tape Bob and Irene McKeown, of Scotland, were leaving the Pasadena, Calif., home of their relatives Tuesday morning when they got the surprise of their lives. In video captured on a surveillance camera, the McKeowns can be seen calmly locking the front door, completely unaware that a bear was lurking just feet away. The bear, however, clearly saw the McKeowns, standing still as the McKeowns locked the door and then following the couple to their car. "Once I closed the door, I turned around and I shouted, 'It's a bear. It's a bear,'" recalled Bob McKeown. The McKeowns escaped their bear encounter with only a slight nick to Bob's leg, but the close encounter with the bear was not a first for the Pasadena area.
