PORTLAND, Ore. — The nation's oldest and largest children's parade took place Wednesday in Portland.

Children from all over the Portland metro area participate in the Portland Rose Festival Junior Parade, dressing up in costumes, walking with their parents or pets, and riding their bikes or sitting on colorful floats. Marching bands and dance teams from local elementary and middle schools provided music and color to the festivities.
