Twice during today's inaugural parade, President Barack Obama and his wife have given spectators the extra bonus they were hoping for. The Obamas left their limousine and walked along part of the parade route, waving and responding to cheers from the crowd.

During the second walk, near the White House, the crowd roared as the Obamas passed in front of bleachers, waving and smiling. Michelle Obama occasionally clapped her hands when she wasn't holding hands with the president.

Vice President Joe Biden and his wife, Jill, also left their limousine to acknowledge the crowds.
